&lt;p>Okun&amp;rsquo;s law is one of macroeconomics&amp;rsquo; most reliable regularities: when output grows, unemployment falls. Yet estimated for Indonesia as a single economy, the relationship does not hold. The reason is aggregation. A vast, heterogeneous archipelago is not one labor market, and a national average quietly cancels out regions that move in opposite directions. The question, then, is not &lt;em>whether&lt;/em> Okun&amp;rsquo;s law holds in Indonesia, but &lt;em>where&lt;/em>.&lt;/p>
&lt;hr>
&lt;h2 id="a-two-step-data-driven-approach">A two-step, data-driven approach&lt;/h2>
&lt;p>Rather than imposing geographic groups in advance (say, &amp;ldquo;West&amp;rdquo; versus &amp;ldquo;East&amp;rdquo;), the authors let the data sort districts into groups with similar growth–unemployment dynamics, then model how those dynamics spill across space. The framework is descriptive — it maps associations, not causal effects.&lt;/p>

&lt;p>The classifier uncovers &lt;strong>four distinct regimes&lt;/strong> that cut across administrative and physical geography — districts in the same group need not be neighbors. Each tells a different story about how growth meets the labor market.&lt;/p>

&lt;tr>
&lt;td style="text-align:left">&lt;strong>Group 1&lt;/strong>&lt;/td>

&lt;td style="text-align:left">&lt;strong>Strong, textbook.&lt;/strong> Growth co-moves with falling unemployment, locally and in neighbors.&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td style="text-align:left">&lt;strong>Group 2&lt;/strong>&lt;/td>
&lt;td style="text-align:left">Capital-intensive hubs — resource zones, mechanized corporate farming&lt;/td>
&lt;td style="text-align:left">Balikpapan, Central Jakarta, rural Java pockets&lt;/td>
&lt;td style="text-align:left">&lt;strong>Reversed.&lt;/strong> Faster growth tracks &lt;em>higher&lt;/em> measured open unemployment.&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td style="text-align:left">&lt;strong>Group 3&lt;/strong>&lt;/td>
&lt;td style="text-align:left">Transitional centers — secondary cities shifting from agriculture to services&lt;/td>
&lt;td style="text-align:left">Cilacap, Indramayu, Malang&lt;/td>
&lt;td style="text-align:left">&lt;strong>Weak.&lt;/strong> Little baseline link; adjustment runs through hours worked, not layoffs.&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td style="text-align:left">&lt;strong>Group 4&lt;/strong>&lt;/td>
&lt;td style="text-align:left">Peripheral markets — thin, isolated rural island economies&lt;/td>
&lt;td style="text-align:left">Remote Papua, East Nusa Tenggara&lt;/td>
&lt;td style="text-align:left">&lt;strong>Negligible.&lt;/strong> Pervasive informality severs the link to formal unemployment.&lt;/td>
&lt;/tr>
&lt;/tbody>
&lt;/table>
&lt;blockquote>
&lt;p>&lt;strong>Why does growth co-move with &lt;em>rising&lt;/em> unemployment in Group 2?&lt;/strong>
Where capital-intensive industry and corporate agriculture dominate, growth often arrives through mechanization that displaces traditional farm labor. As displaced workers leave informal or family work to look for formal wage jobs, they enter the statistics as &amp;ldquo;openly unemployed.&amp;rdquo; Measured unemployment rises alongside output through search frictions and skills mismatch — not because growth itself destroys jobs.&lt;/p>
&lt;/blockquote>
&lt;hr>
&lt;h2 id="robustness-at-the-province-level">Robustness at the province level&lt;/h2>
&lt;p>To check that the pattern is not an artifact of district-level noise, the authors re-run the framework on 34 provinces. It reproduces a similar structure, now in three regimes:&lt;/p>
&lt;ul>
&lt;li>&lt;strong>Diversified, demand-rich provinces&lt;/strong> — industrial and consumer hubs with a steep Okun coefficient of $-0.262$.&lt;/li>
&lt;li>&lt;strong>Agricultural commodity heartlands&lt;/strong> — large corporate plantations where growth is locally &amp;ldquo;jobless&amp;rdquo; but generates spillovers to neighbors.&lt;/li>
&lt;li>&lt;strong>Commodity-frontier enclaves&lt;/strong> — thin labor markets tied to mining and heavy industry, with a near-flat coefficient of $-0.033$.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h2 id="spatial-spillovers-matter">Spatial spillovers matter&lt;/h2>
&lt;p>Labor-market adjustment does not stop at district borders. Changes in unemployment are correlated across neighboring districts ($\rho = 0.135$), so a growth shock in one place reaches the next.&lt;/p>
&lt;p>Separating local responses from spillovers is what makes this visible. In Group 1, growth is associated with lower unemployment at home (direct association $-0.112$) &lt;em>and&lt;/em> with lower unemployment next door (indirect spillover $-0.077$). A model that ignores spillovers would miss roughly the entire neighboring footprint of regional momentum.&lt;/p>
&lt;hr>
&lt;h2 id="key-takeaways">Key takeaways&lt;/h2>
&lt;ul>
&lt;li>&lt;strong>Aggregate estimates mislead.&lt;/strong> A single national Okun coefficient averages over regimes whose growth–unemployment associations point in opposite directions.&lt;/li>
&lt;li>&lt;strong>Diversified hubs are the engine.&lt;/strong> In metropolitan and smallholder-plantation districts (Group 1), output gains translate most reliably into job creation, at home and nearby.&lt;/li>
&lt;li>&lt;strong>Structural change reshapes absorption.&lt;/strong> Moving from family farming to mechanized corporate agriculture lowers how many workers the local economy absorbs per unit of output.&lt;/li>
&lt;li>&lt;strong>Informality hides slack.&lt;/strong> In peripheral regions (Group 4), open-unemployment figures understate distress because people fall back on underemployment and informal work.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h2 id="open-questions">Open questions&lt;/h2>
&lt;ol>
&lt;li>If capital-intensive growth (Group 2) keeps pushing displaced farm workers into open unemployment, how can local governments build training pipelines that move them into modern service jobs?&lt;/li>
&lt;li>Given how much of the total association runs through spillovers in labor-absorbing zones, should planning shift from isolated district targets toward coordinated multi-district economic corridors?&lt;/li>
&lt;/ol>

&lt;ul>
&lt;li>District-level minimum wages after 2001&lt;/li>
&lt;li>Large cross-border wage differentials&lt;/li>
&lt;li>High daily mobility within Jabodetabek&lt;/li>
&lt;/ul>
&lt;p>Following Indonesia’s fiscal decentralization, districts in Jabodetabek set distinct minimum wages. The 2015 distribution shows substantial variation across adjacent districts. Because commuting costs are lower than relocation costs, workers may respond to wage gaps by crossing district borders rather than migrating permanently.&lt;/p>
&lt;hr>
&lt;h2 id="-motivation-2-why-commuting-matters">🚆 Motivation 2: Why Commuting Matters&lt;/h2>
&lt;ul>
&lt;li>3.5–4.4 million daily commuters&lt;/li>
&lt;li>21% of formal workers commute&lt;/li>
&lt;li>Employment data reflect residence, not workplace&lt;/li>
&lt;/ul>
&lt;p>During 2011–2015, commuting was widespread and predominantly in-person. Since labor surveys record residential location, ignoring cross-district mobility may bias estimates of minimum-wage effects. Policy evaluation must consider spillovers across administrative borders.&lt;/p>
&lt;hr>
&lt;h2 id="-data-and-methods">📊 Data and Methods&lt;/h2>
&lt;ul>
&lt;li>Sakernas pooled cross-sections (2011–2015)&lt;/li>
&lt;li>Binomial logit model of commuting probability&lt;/li>
&lt;li>Home vs. cross-border minimum wages&lt;/li>
&lt;li>District and year fixed effects&lt;/li>
&lt;/ul>
&lt;p>The analysis exploits district-pair comparisons within a single metropolitan labor market. The key variables are real minimum wages at home and neighboring districts. The specification controls for demographics, macroeconomic factors, and spatial spillovers (SLX model).&lt;/p>
&lt;hr>
&lt;h2 id="-education-heterogeneity">🎓 Education Heterogeneity&lt;/h2>
&lt;ul>
&lt;li>+0.9 ppts commuting per 100k IDR increase (average)&lt;/li>
&lt;li>College graduates: +1.7 ppts&lt;/li>
&lt;li>&amp;lt; High school: +0.3 ppts&lt;/li>
&lt;/ul>
&lt;p>Cross-border minimum wages significantly raise commuting probabilities. Responses are strongest among higher-educated workers, suggesting they benefit more from wage differentials and face lower mobility frictions.&lt;/p>
&lt;hr>
&lt;h2 id="-income-heterogeneity">💰 Income Heterogeneity&lt;/h2>
&lt;ul>
&lt;li>High-income workers most responsive (+1.9 ppts)&lt;/li>
&lt;li>Minimum-wage earners moderately responsive&lt;/li>
&lt;li>Below-minimum earners: no significant effect&lt;/li>
&lt;/ul>
&lt;p>Commuting responses concentrate among workers earning above the minimum wage. Non-compliance weakens incentives for low-wage earners, highlighting institutional constraints in developing-country labor markets.&lt;/p>
&lt;hr>
&lt;h2 id="-spatial-spillovers">🌐 Spatial Spillovers&lt;/h2>
&lt;ul>
&lt;li>Neighboring wages affect commuting&lt;/li>
&lt;li>Evidence robust to SLX model&lt;/li>
&lt;li>Spillovers vary across worker groups&lt;/li>
&lt;/ul>
&lt;p>Spatial lag models confirm that district policies generate measurable cross-border effects. While magnitude varies with specification, the qualitative conclusion remains consistent: wage-setting fragmentation transmits local shocks across the metropolitan system.&lt;/p>
&lt;hr>
&lt;h2 id="-policy-implications">⚖️ Policy Implications&lt;/h2>
&lt;ul>
&lt;li>Decentralized wage-setting creates internal borders&lt;/li>
&lt;li>Spillovers may distort employment statistics&lt;/li>
&lt;li>Coordination across districts is essential&lt;/li>
&lt;/ul>
&lt;p>Minimum wage differentials shape mobility patterns in integrated urban regions. Policymakers should consider harmonized frameworks or bounded dispersion rules to balance local autonomy with labor-market integration.&lt;/p>
&lt;hr>
&lt;h2 id="-key-takeaways">🔎 Key Takeaways&lt;/h2>
&lt;ul>
&lt;li>Cross-border wage gaps increase commuting&lt;/li>
&lt;li>Effects heterogeneous by education and income&lt;/li>
&lt;li>Ignoring mobility biases policy evaluation&lt;/li>
&lt;li>Regional coordination improves welfare design&lt;/li>
&lt;/ul>
&lt;p>The evidence indicates that commuting is a key adjustment margin in decentralized labor markets. Incorporating worker mobility is essential for credible minimum-wage evaluation in metropolitan regions such as Jabodetabek.&lt;/p></description></item><item><title>Harmonized luminosity and economic activity across provinces in China: Cross-sectional differences, regional time series, and inequality dynamics</title><link>https://carlos-mendez.org/articles/20241219-ae/</link><pubDate>Sat, 20 Dec 2025 00:00:00 +0000</pubDate><guid>https://carlos-mendez.org/articles/20241219-ae/</guid><description>&lt;div class="alert alert-note">

&lt;h3 id="-introduction">🌏 Introduction&lt;/h3>
&lt;ul>
&lt;li>Rapid economic growth, yet persistent poverty (17.8% below national line in 2019)&lt;/li>
&lt;li>Traditional poverty data: outdated, costly, and coarse&lt;/li>
&lt;li>Poverty: not only income but health, education, and living standards (MPI framework)&lt;/li>
&lt;/ul>
&lt;p>Notes: Cambodia has seen strong growth but poverty remains. The study applies a multidimensional approach aligned with the Global MPI to capture deprivations beyond income, focusing on education, health, and living standards.&lt;/p>
&lt;hr>
&lt;h3 id="-research-objectives">📊 Research Objectives&lt;/h3>
&lt;ul>
&lt;li>Use &lt;strong>big earth data&lt;/strong> + &lt;strong>CSES survey&lt;/strong> + &lt;strong>machine learning&lt;/strong>&lt;/li>
&lt;li>Map &lt;strong>10 poverty indicators&lt;/strong> across &lt;strong>3 MPI dimensions&lt;/strong>&lt;/li>
&lt;li>Generate &lt;strong>high-resolution poverty maps&lt;/strong>&lt;/li>
&lt;li>Support &lt;strong>targeted, cost-effective policy interventions&lt;/strong>&lt;/li>
&lt;/ul>
&lt;p>Notes: The aim is to integrate spatial and survey data using AI/ML to produce detailed poverty maps. This helps policymakers allocate resources efficiently and identify local vulnerabilities.&lt;/p>
&lt;hr>
&lt;h3 id="-literature--motivation">📚 Literature &amp;amp; Motivation&lt;/h3>
&lt;ul>
&lt;li>Household surveys = costly, infrequent, spatially coarse&lt;/li>
&lt;li>Nighttime lights &amp;amp; satellite imagery → proxies for poverty&lt;/li>
&lt;li>Machine Learning (RF, XGBoost, CNNs) improve predictions&lt;/li>
&lt;li>Gap: Few studies integrate &lt;strong>survey + EO data&lt;/strong> for &lt;strong>multidimensional poverty&lt;/strong>&lt;/li>
&lt;/ul>
&lt;p>Notes: Prior research shows satellites and ML can help predict poverty, but integration with socioeconomic surveys for multidimensional poverty is limited. This study fills that gap.&lt;/p>
&lt;hr>
&lt;h3 id="-data-sources">🗂️ Data Sources&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>CSES survey&lt;/strong> (10k households) – health, education, housing, income&lt;/li>
&lt;li>&lt;strong>Satellite &amp;amp; EO data&lt;/strong> – nightlights, land cover, population density&lt;/li>
&lt;li>&lt;strong>Infrastructure data&lt;/strong> – roads, schools, hospitals, utilities&lt;/li>
&lt;li>&lt;strong>Building footprints&lt;/strong> – 3.8M residential/commercial buildings&lt;/li>
&lt;/ul>
&lt;p>Notes: A wide set of data was used: CSES for household info, EO data for environment and infrastructure, and building footprints to scale down predictions to household level.&lt;/p>
&lt;hr>
&lt;h3 id="-methodology">⚙️ Methodology&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>Random Forest&lt;/strong> model for classification&lt;/li>
&lt;li>Predicts &lt;strong>deprivation probability&lt;/strong> for each indicator&lt;/li>
&lt;li>Training &amp;amp; validation split (90/10)&lt;/li>
&lt;li>Outputs: household &amp;amp; regional deprivation maps&lt;/li>
&lt;/ul>
&lt;p>Notes: The Random Forest algorithm was selected due to robustness and ability to process mixed data types. Models produce probability maps that can be aggregated at township, district, or province level.&lt;/p>
&lt;hr>
&lt;h3 id="-mpi-indicators">📑 MPI Indicators&lt;/h3>
&lt;p>&lt;strong>Health (2):&lt;/strong> Food consumption, access to healthcare&lt;/p>
&lt;p>&lt;strong>Education (2):&lt;/strong> Attainment, school attendance&lt;/p>
&lt;p>&lt;strong>Living Standards (6):&lt;/strong> Cooking fuel, sanitation, water, electricity, housing, assets&lt;/p>
&lt;p>Notes: Ten indicators were chosen following the Global MPI. Equal weights applied across three main dimensions. These indicators reflect SDG priorities like education, health, clean water, and energy.&lt;/p>
&lt;hr>
&lt;h3 id="-results--variable-importance">📈 Results – Variable Importance&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>Nighttime lights&lt;/strong> = key predictor across indicators&lt;/li>
&lt;li>&lt;strong>Population density&lt;/strong> &amp;amp; &lt;strong>road networks&lt;/strong> also significant&lt;/li>
&lt;li>Strongest predictions: &lt;strong>cooking fuel, clean water, sanitation, electricity&lt;/strong>&lt;/li>
&lt;li>Weak predictions: &lt;strong>school attendance, healthcare, assets&lt;/strong>&lt;/li>
&lt;/ul>
&lt;p>Notes: Nightlights and population density best explain deprivation. Infrastructure access is also crucial. Indicators with spatial correlation (e.g., utilities) performed better than those tied to household-specific conditions.&lt;/p>
&lt;hr>
&lt;h3 id="-results--spatial-poverty-patterns">🗺️ Results – Spatial Poverty Patterns&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>Urban centers&lt;/strong>: Phnom Penh, Siem Reap, Battambang → low deprivation&lt;/li>
&lt;li>&lt;strong>Remote provinces&lt;/strong>: Preah Vihear, Ratanakiri, Mondulkiri → high deprivation&lt;/li>
&lt;li>Poverty lower near &lt;strong>main roads &amp;amp; borders&lt;/strong> (trade effects)&lt;/li>
&lt;/ul>
&lt;p>Notes: Spatial maps show concentration of deprivation in remote, poorly connected regions. Urban and border areas with infrastructure show lower poverty.&lt;/p>
&lt;hr>
&lt;h3 id="-discussion">💡 Discussion&lt;/h3>
&lt;ul>
&lt;li>Spatial ML useful but limited for indicators with weak spatial signals&lt;/li>
&lt;li>Household survey data not designed for ML → location approximation issues&lt;/li>
&lt;li>Need for richer survey integration (e.g., accessibility questions)&lt;/li>
&lt;li>EO + ML offer &lt;strong>granular, dynamic poverty mapping&lt;/strong>&lt;/li>
&lt;/ul>
&lt;p>Notes: While promising, ML struggles when data lack spatial correlation. Improved survey design can enhance integration. This hybrid approach shows potential for real-time, fine-grained poverty monitoring.&lt;/p>
&lt;hr>
&lt;h3 id="-conclusion">✅ Conclusion&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>10 MPI indicators mapped&lt;/strong> using EO + survey + ML&lt;/li>
&lt;li>Best results for &lt;strong>infrastructure-related deprivations&lt;/strong>&lt;/li>
&lt;li>Enables &lt;strong>household-level poverty estimates&lt;/strong>&lt;/li>
&lt;li>Supports &lt;strong>SDGs&lt;/strong>: No Poverty, Quality Education, Health, Clean Water, Energy&lt;/li>
&lt;li>Future research: spatial autocorrelation, inequality decomposition, advanced AI&lt;/li>
&lt;/ul>
&lt;p>Notes: This work shows how AI and EO data complement traditional surveys to map multidimensional poverty. Future directions include advanced spatial analysis and deep learning models for better accuracy.&lt;/p></description></item><item><title>Bayesian average of classical estimates for panel data: Can the puzzle of the shape of the regional Kuznets curve be solved?</title><link>https://carlos-mendez.org/articles/20250605-ee/</link><pubDate>Thu, 05 Jun 2025 00:00:00 +0000</pubDate><guid>https://carlos-mendez.org/articles/20250605-ee/</guid><description>&lt;div style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;">

&lt;li>Identify determinants that consistently drive regional inequality&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h2 id="-methodology-highlights">🛠️ Methodology Highlights&lt;/h2>
&lt;ul>
&lt;li>
&lt;p>&lt;strong>Search space:&lt;/strong> 14 candidate regressors → 2¹⁴ = &lt;strong>16 384&lt;/strong> models, each estimated with two-way (country + period) fixed effects.&lt;/p>
&lt;/li>
&lt;li>
&lt;p>&lt;strong>Robustness sweep:&lt;/strong> Allowing four fixed-effects options (none, time, country, two-way) expands the universe to &lt;strong>65 536&lt;/strong> models; posterior model probabilities (PMPs) concentrate entirely on the two-way specification.&lt;/p>
&lt;/li>
&lt;li>
&lt;p>&lt;strong>Bayesian Averaging of Classical Estimates (BACE):&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Retains simple FE-OLS for every model—no heavy MCMC.&lt;/li>
&lt;li>Translates each model’s BIC into an approximate marginal likelihood.&lt;/li>
&lt;li>Uses a uniform prior so PMPs sum to 1, then forms &lt;strong>probability-weighted averages&lt;/strong> for all coefficients, predictions, and derivatives.&lt;/li>
&lt;/ul>
&lt;/li>
&lt;li>
&lt;p>&lt;strong>Variable screening:&lt;/strong> Posterior Inclusion Probability (PIP) highlights robust determinants—“substantial evidence” at PIP ≥ 0.75, “strong” at PIP ≥ 0.90.&lt;/p>
&lt;/li>
&lt;li>
&lt;p>&lt;strong>Curve peaks:&lt;/strong> Inequality turning points come from the BACE-weighted derivative of the cubic GDP polynomial, with analytic standard errors for credible bands.&lt;/p>
&lt;/li>
&lt;li>
&lt;p>&lt;strong>Validation:&lt;/strong> Monte-Carlo experiments with a known data-generating process show BACE pinpoints the correct fixed-effects structure and true drivers, underscoring the method’s reliability.&lt;/p>

&lt;li>Territorial violence in Brazil exhibits strong spatial patterns.&lt;/li>
&lt;li>Builds on Ingram &amp;amp; Marchesini da Costa (2019) using MGWR.&lt;/li>
&lt;li>Goal: Explore spatial heterogeneity &amp;amp; scale effects on lethal violence.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-methodological-innovations">🧪 Methodological Innovations&lt;/h3>
&lt;ul>
&lt;li>Used &lt;strong>cloud-based computational notebooks&lt;/strong> for full replication and open science.&lt;/li>
&lt;li>Adopted &lt;strong>Multiscale Geographically Weighted Regression (MGWR)&lt;/strong>.&lt;/li>
&lt;li>Identified persistent &lt;strong>geographical violence clusters&lt;/strong>.&lt;/li>
&lt;li>Applied a &lt;strong>multiple testing correction&lt;/strong> to ensure robustness.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-data-overview">📊 Data Overview&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>Unit of analysis&lt;/strong>: 5,562 municipalities (2007–2012)&lt;/li>
&lt;li>&lt;strong>Dependent variable&lt;/strong>: Change in homicide rate (Δ 2011–2012 vs. 2007–2008)&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>Political Variables&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Margin of victory (%)&lt;/li>
&lt;li>Party alignment with state governor&lt;/li>
&lt;li>Vote abstention (%)&lt;/li>
&lt;li>Mayor&amp;rsquo;s party identification:
&lt;ul>
&lt;li>&lt;strong>Brazilian Democratic Movement Party (PMDB)&lt;/strong>&lt;/li>
&lt;li>&lt;strong>Brazilian Social Democracy Party (PSDB)&lt;/strong>&lt;/li>
&lt;li>&lt;strong>Workers&amp;rsquo; Party (PT)&lt;/strong>&lt;/li>
&lt;/ul>
&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>Socioeconomic Variables&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Population density&lt;/li>
&lt;li>Young male population (%)&lt;/li>
&lt;li>Gini index (income inequality)&lt;/li>
&lt;li>Human Development Index (HDI)&lt;/li>
&lt;li>Households headed by single mothers (%)&lt;/li>
&lt;li>Adult employment rate (%)&lt;/li>
&lt;li>Bolsa Família eligibility (%)&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-modeling-frameworks">🧭 Modeling Frameworks&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>OLS&lt;/strong>: Global effect estimates.&lt;/li>
&lt;li>&lt;strong>GWR&lt;/strong>: Localized effect estimates with a single spatial scale.&lt;/li>
&lt;li>&lt;strong>MGWR&lt;/strong>: Localized effect estimates　with multiple spatial scales.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-ols-results">🔍 OLS Results&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>PMDB&lt;/strong> mayors → Increased violence.&lt;/li>
&lt;li>&lt;strong>PT&lt;/strong> &amp;amp; &lt;strong>PSDB&lt;/strong> → No consistent effect.&lt;/li>
&lt;li>Vote abstention → Strongly linked to higher homicide rates.&lt;/li>
&lt;li>Unexpected: GINI index showed negative correlation.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-gwr-results-political-variables">🗺️ GWR Results: Political Variables&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>PMDB&lt;/strong>: Positive correlation in the northeast.&lt;/li>
&lt;li>&lt;strong>PT&lt;/strong>: Violence-reducing in many regions.&lt;/li>
&lt;li>&lt;strong>PSDB&lt;/strong>: Mixed effects—north (↑), south (↓).&lt;/li>
&lt;li>Abstention: Violence-increasing in several regions.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-gwr-results-socioeconomic-variables">🧮 GWR Results: Socioeconomic Variables&lt;/h3>
&lt;ul>
&lt;li>Population density &amp;amp; Bolsa Família → Heterogeneous effects.&lt;/li>
&lt;li>Young male % &amp;amp; single mothers → Generally increased violence.&lt;/li>
&lt;li>Effect direction &amp;amp; significance vary spatially.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-mgwr-results-political-variables">🗺️ MGWR Results: Political Variables&lt;/h3>
&lt;ul>
&lt;li>&lt;strong>PMDB&lt;/strong> still ↑ violence in northeast.&lt;/li>
&lt;li>&lt;strong>PSDB&lt;/strong> now only ↓ violence in southern Brazil.&lt;/li>
&lt;li>&lt;strong>PT&lt;/strong> effect mostly disappears after statistical corrections.&lt;/li>
&lt;li>Abstention: Consistent with GWR in some regions.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-mgwr-results-socioeconomic-variables">🌆 MGWR Results: Socioeconomic Variables&lt;/h3>
&lt;ul>
&lt;li>Bolsa Família: No significant impact.&lt;/li>
&lt;li>Young male %: Significant across more areas due to large spatial scale.&lt;/li>
&lt;li>Population density &amp;amp; single mothers: Small-scale, heterogeneous influence.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-mapping-residual-clusters">📌 Mapping Residual Clusters&lt;/h3>
&lt;ul>
&lt;li>Intercept mapping (MGWR): Reveals &lt;strong>unexplained clusters&lt;/strong>.&lt;/li>
&lt;li>Central Brazil: Positive residuals → unobserved structural factors?&lt;/li>
&lt;li>South &amp;amp; Central-East: Negative residuals.&lt;/li>
&lt;/ul>
&lt;hr>
&lt;h3 id="-conclusion">🧩 Conclusion&lt;/h3>
&lt;ul>
&lt;li>MGWR provides nuanced spatial insights.&lt;/li>
&lt;li>Confirms heterogeneity in violence determinants.&lt;/li>
&lt;li>Suggests need for regional, tailored policy interventions.&lt;/li>
&lt;li>Further investigation needed into residual violence clusters.&lt;/li>

&lt;p>&lt;strong>🛰️ Introduction &amp;amp; Context&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Challenge: Limited subnational GDP data in Vietnam before 2010&lt;/li>
&lt;li>Need: Long-term data for economic development analysis&lt;/li>
&lt;li>Solution: Predict GDP using remote sensing &amp;amp; machine learning&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>🌌 Data Sources Used&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Official GDP data (2010-2020)&lt;/li>
&lt;li>Nighttime Lights (NTL): Harmonized DMSP &amp;amp; VIIRS-like datasets&lt;/li>
&lt;li>Agricultural land data (ESA)&lt;/li>
&lt;li>Climate data: Temperature &amp;amp; precipitation (CRU)&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>🧠 Machine Learning Approach&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Six algorithms compared:
&lt;ul>
&lt;li>Artificial Neural Networks (ANN)&lt;/li>
&lt;li>Random Forest (RF)&lt;/li>
&lt;li>Support Vector Machines (SVM)&lt;/li>
&lt;li>K-Nearest Neighbors (KNN)&lt;/li>
&lt;li>Ridge Regression&lt;/li>
&lt;li>eXtreme Gradient Boosting (XGBoost)&lt;/li>
&lt;/ul>
&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>🔦 Key Findings&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Predictions consistent across different nighttime datasets&lt;/li>
&lt;li>Ridge Regression chosen for final model&lt;/li>
&lt;li>Important features: Temperature &amp;amp; Agricultural Land more influential than NTL&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>🌍 Application &amp;amp; Significance&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Created GDP data from 1992-2009&lt;/li>
&lt;li>Enables detailed long-term analysis of regional economic trends&lt;/li>
&lt;li>Assists policymakers and researchers in addressing regional inequality and growth&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>⚠️ Limitations&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Remote sensing measurement/calibration discrepancies&lt;/li>
&lt;li>Dependence on official GDP benchmarks&lt;/li>
&lt;li>Interpretability challenges of machine learning methods&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>🚀 Future Research Directions&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Explore additional remote sensing datasets&lt;/li>
&lt;li>Estimate broader socioeconomic indicators&lt;/li>
&lt;li>Improve models with larger datasets&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>🎯 Conclusion&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>Machine learning + Remote sensing effectively address subnational data gaps&lt;/li>
&lt;li>New dataset supports informed economic policy decisions&lt;/li>
&lt;li>Potentially replicable method for other developing countries&lt;/li>
