   What is the effect of the 2009 recentralization on whether a commune has public transport?

   malesky_impact_of_recentralization (agent)

   This dataset is a commune–year panel for rural Vietnam built from the 2006, 2008, and 2010 Vietnam Household Living Standards Survey (VHLSS) commune questionnaires and merged with district– and province–level identifiers for the District People’s Council (DPC) abolition pilot. Each observation corresponds to a rural commune in a given survey year, with variables describing geography, survey timing, infrastructure, public services, agriculture, nonfarm activity, migration, credit access, health and education facilities, land use, sectoral structure, and treatment status in the recentralization experiment. Variables: tinh: Province code identifying the province in which the commune is located, used to link communes to provincial characteristics and the treatment assignment strata. huyen: District code indicating the district (second‑tier unit) in which the commune resides, which is the level at which District People’s Councils were abolished in treated areas. xa: Commune code identifying the basic local administrative unit observed in the VHLSS commune survey. madt: Survey or commune identifier from the VHLSS used to uniquely index communes within survey waves and to merge across questionnaire modules. ngaydt / thangdt: Day and month of the commune interview date, recording when the VHLSS commune questionnaire was administered in the field. ngayct / thangct: Day and month of completion for the commune questionnaire or related verification, capturing timing of finalization of commune‑level data. m1c1–m1c10, m1c11a–m1c11c, m1c12a–m1c12c, m1c13–m1c15: Original VHLSS module‑1 commune checklist items capturing basic commune characteristics and public services (e.g., infrastructure, social programs, local projects), coded as binary indicators or shares and later combined into sector‑specific indices (infrastructure, agricultural services, health, education, communications, household business support). m3c1–m3c5, m3c2, m3c2a1–m3c2a3, m3c3, m3c4a–m3c4c, m3c4a1–m3c4a3, m3c5: Original VHLSS module‑3 items on nonfarm employment, local economic activity, and social problems, providing commune‑level indicators of nonfarm jobs, business conditions, and related constraints used in constructing household‑business development outcomes. roadvmonth: Measure of road or transport–related investment or maintenance at the commune level (e.g., months with road work or road access), capturing intensity of road service over the year. totalhh: Total number of households in the commune, used to construct household shares for service coverage (e.g., share of households receiving agricultural extension or health fee support). improve: Indicator summarizing whether overall living standards or socio‑economic conditions in the commune have improved over a recent period as reported by local authorities. poorhh: Number or share of poor households in the commune according to official poverty classification, providing a commune‑level poverty rate. geogra: Categorical or coded measure of the commune’s geographic type (e.g., lowland, highland, coastal, remote), used as a control for structural conditions in service delivery. pro135: Indicator for whether the commune is covered by Vietnam’s Program 135 or other national poverty‑targeted programs, capturing exposure to special development support. remotecom: Indicator for whether the commune is classified as remote or especially difficult, reflecting geographic disadvantage and higher costs of service provision. credithh: Number or share of households receiving formal or semi‑formal credit support, used as an outcome in the household‑business development index. povrate: Commune‑level poverty rate constructed from poor households over total households or from official statistics, summarizing local deprivation. pro1–pro6: Set of indicators capturing the presence or implementation of different centrally funded socio‑economic projects or programs in the commune (e.g., transport, health, education,

availability of extension staff or centers), feeding into the agricultural services index. roadv / goodroadv / droadv: Measures of village‑level road access and quality, including whether villages are connected by all‑weather roads, the share of “good” roads, and changes in road conditions across years. transport: Indicator for whether the commune has public transport services (e.g., bus or other collective transport), one of the treated infrastructure outcomes. post / market / electricity / culture / broadcast / irrigation: Binary or categorical indicators for the presence of key public facilities in the commune—post offices, markets, electricity grid connections, cultural houses, broadcast stations, and irrigation systems—used as inputs to infrastructure and communications indices. prischool / lseschool / useschool / kgarten: Indicators for the existence or accessibility of primary, lower‑secondary, upper‑secondary schools, and kindergartens in the commune, forming the base of the education services index. nonfarm / nonfarme: Measures of nonfarm employment and nonfarm enterprises in the commune, capturing diversification of local livelihoods away from agriculture. emproblem: Indicator summarizing key employment problems in the commune (e.g., underemployment, lack of local jobs) as reported by commune leaders. migration_in / migration_out: Commune‑level counts or indicators for in‑migration and out‑migration, reflecting population flows and labor mobility. population: Total population of the commune, used to scale services and to construct population density. rm2c7a–rm2c7g (rm2c7a–rm2c7f, rm2c7g): Group of items capturing specific social or economic problems reported by commune authorities (e.g., crime, environmental issues, social evils), providing contextual information on local challenges. villbusi / numbusi: Indicators for whether the commune has village‑level household businesses and the total number of household businesses, used in the household business development index. agrrise: Indicator for whether agricultural production in the commune has recently risen, reflecting local economic trends in farming. cleanwater / tapwater: Indicators for access to clean water sources and piped or tap water in the commune, often used as complementary infrastructure or health‑related outcomes. agrvisit / plant_s / animal_s: Measures of agricultural extension intensity—such as the number of extension visits (agrvisit) and the presence of plant and animal husbandry support services—capturing the depth of agricultural support. polluted: Indicator for whether the commune reports pollution problems, capturing environmental conditions that may co‑vary with infrastructure and industrialization. nfworkers: Number of nonfarm workers in the commune workforce, summarizing structural change in local employment. hecenter1–hecenter5, hecenter: Indicators for the existence of different types of local health centers or facilities and an aggregate indicator summarizing whether any such health center is present, feeding into the health services index. d_hecenter1–d_hecenter5: Change indicators tracking whether specific types of health centers have appeared or disappeared between survey waves, capturing dynamics of health infrastructure. lender1–lender7, lender1a–lender6a: Indicators for the presence or use of multiple types of credit providers in the commune (e.g., different institutional or informal lenders) and their activity, providing a detailed picture of local credit markets for households and small firms. d_lender1–d_lender7, d_lender1a–d_lender6a: Change variables indicating expansions or contractions in access to the corresponding lender types over time, used to study evolution of credit access. land1–land5: Areas or shares of different categories of agricultural land in the commune (e.g., by land type or use class), summarizing the structure of local land resources. land1_irr /

locality across survey years. province_name / district_name / tentinh / tinh_new: Text and alternative numeric codes for provinces and districts, allowing transparent labeling of administrative units and alignment with official administrative changes. treatment: Indicator equal to 1 for communes in districts where District People’s Councils were abolished in the national pilot and 0 for communes
