   How much did logged municipal property tax (IPTU) revenue change after municipalities that updated the cadastre in 2014, relative to municipalities that had not yet updated by 2014?

   ds_0003 (agent)

   | Variable Name | Description | | --- | --- | | c6_ibge | Six-digit IBGE municipality identifier used in Brazilian statistical and administrative systems to uniquely identify each locality. | | codigouf | Numeric code of the state (Unidade da Federação) in which the municipality is located. | | year | Calendar year of observation (primarily 2004–2015). | | term | Start year of the mayoral electoral term associated with the record when available (four-year cycles in Brazil). | | cad_update | Indicator equal to 1 in and after years when the municipality reports having completed a comprehensive cadastre (land-parcel register) update; 0 otherwise. | | planta_update | Indicator equal to 1 in years when the municipality reports revising the generic land valuation schedule (Planta Genérica de Valores) used to assess property values for taxation; 0 otherwise. | | iptu_law_update | Indicator equal to 1 in years when the municipality reports reforming or updating its local property tax (IPTU) law or regulations; 0 otherwise. | | logiptu | Natural log of annual IPTU (urban property tax) revenue collected by the municipality, in Brazilian reais (R$). | | logissqn | Natural log of annual ISSQN (services tax) revenue collected by the municipality, in Brazilian reais (R$). | | Llogtransfers | One-year lag of the natural log of total intergovernmental transfers received by the municipality (federal and state transfers), in Brazilian reais (R$). | | pre_2004_cad_update_yr | Year of the last comprehensive municipal cadastre update reported prior to 2004. | | t | Integer index for years relative to the last pre-2004 cadastre update (e.g., 0 in the update year, positive thereafter, negative before). | | switchcadaster | Binary flag tied to cadastre timing that marks the reference update year used to construct relative-year indicators. | | F3switchcadaster | Indicator equal to 1 three years before the referenced cadastre update; 0 otherwise. | | F2switchcadaster | Indicator equal to 1 two years before the referenced cadastre update; 0 otherwise. | | Lswitchcadaster | Indicator equal to 1 one year after the referenced cadastre update; 0 otherwise. | | L2switchcadaster | Indicator equal to 1 two years after the referenced cadastre update; 0 otherwise. | | L3cad_update | Indicator equal to 1 three years after the referenced cadastre update; 0 otherwise. | | F4cad_update | Indicator equal to 1 four years before the referenced cadastre update; 0 otherwise. | | anyswitch_period | Municipality-level flag equal to 1 for places that experience a change in cadastre-update status within the analysis window; 0 for those that remain in the same status throughout. | | loggdppc | Natural log of municipal GDP per capita, in Brazilian reais (R$), based on national accounts statistics. | | logdespobras | Natural log of annual municipal expenditures on public works (obras), in Brazilian reais (R$). | | id_c6_electoral_term | Concatenated identifier for municipality-by-electoral-term (c6_ibge + term start year), allowing records to be grouped by mayoral administration. | | yr_adm | Year index within the current mayoral administration (typically 1–4), counting elapsed years since the start of the term; resets at the beginning of a new administration. | Dataset Context: This municipality–year panel brings together administrative and survey-based information to follow local public finance and land administration practices across Brazil during the mid-2000s to mid-2010s. Fiscal data on locally collected taxes and expenditures are drawn from Brazil’s Treasury systems—FINBRA for earlier years and SICONFI for later years—harmonized to annual totals and recorded in Brazilian reais. These sources capture the main municipal own-revenue streams, notably the urban property tax (IPTU) and the services tax (ISSQN), as well as the flows of intergovernmental transfers from federal and state governments. Continuous variables appearing in logarithms are natural logs of annual amounts. Information on land administration comes from IBGE’s Pesquisa de Informações Básicas Municipais (MUNIC), an institutional survey fielded to all municipalities. MUNIC asks local governments about the status and timing of their real estate cadastre—an official register of parcels, ownership, and fiscal valuation—and related legal or administrative changes. The dataset records whether and when municipalities report: conducting a comprehensive cadastre update; revising the generic valuation schedule (Planta Genérica de Valores) used to appraise taxable values; and reforming local property tax rules. Because the cadastre underpins assessment and billing for the IPTU, these administrative markers help track when municipalities refresh the underlying property records and valuation parameters. Socioeconomic indicators such as GDP per capita are taken from IBGE national accounts and municipal statistics, allowing fiscal figures to be interpreted in light of local economic conditions. Additional budget aggregates, like spending on public works, come from the same Treasury systems as revenue data, providing a view of how local governments allocate resources. The panel further includes identifiers that align fiscal and administrative observations with mayoral terms. Brazil’s municipalities elect mayors to four-year administrations; the dataset includes a composite municipality-by-term key and an index of years elapsed within each administration to facilitate analyses organized by political cycles. Finally, a small set of variables encodes the calendar position of observations relative to reported cadastre updates (e.g., indicators for specific years before or after an update). These timing markers are constructed from MUNIC responses on the last update year and allow users to describe patterns around the moments when registers are overhauled. Overall, the dataset enables longitudinal tracking of land administration practices, revenue collection, and budgetary activity across thousands of municipalities under a common institutional framework.
