Alternatively, weights can be specified using {help svyset}. {title:Required packages} {pstd} {cmd:ceqfiscal} requires installation of {cmd:quantiles} (Osorio, 2007); to install, {stata ssc install quantiles:ssc install quantiles}. {title:Description} {pstd} {cmd:ceqfiscal} calculates summary statistics and detailed information by decile, income group, centile, and income bin for fiscal interventions (taxes, transfers, and subsidies), where deciles, groups, centiles, and bins are defined holding the income concept fixed within each sheet. Hence, {cmd:ceqfiscal} produces one sheet for each of the CEQ core income concepts; the income concept defining the ranking of each sheet will be referred to in this help file as the ranking variable. Summary statistics include the mean, median, standard deviation, and measures for each fiscal intervention with respect to the ranking variable: its concentration coefficient and Kakwani coefficient. The detailed information by decile, income group, centile, and income bin includes--for each fiscal intervention--total received or paid in local currency units (preferably per year) and PPP dollars per day, per capita amount received or paid in local currency (preferably per year) and PPP dollars per day, concentration shares, cumulative concentration shares, and fiscal incidence with respect to the ranking variable. {pstd} The fiscal interventions are specified using fiscal intervention options. Note that each option takes a {varlist} that can (and often should) have greater than one variable: the variables provided should be as disaggregated as possible. For example, there might be survey questions about ten different direct cash transfer programs; each of these would be a variable, and all ten variables would be included with the {opth dtr:ansfers(varlist)} option. Contributory pensions are specified by {opth p:ensions(varlist)}, direct transfers by {opth dtr:ansfers(varlist)}, direct taxes (not including contributions) by {opth dtax:es(varlist)}}, contributions (including variables for both employer and employee contributions if applicable) by {opth co:ntribs(varlist)}, indirect subsidies by {opth su:bsidies(varlist)}, indirect taxes by {opth indtax:es(varlist)}, health benefits by {opth health(varlist)}, educaiton benefits by {opth educ:ation(varlist)}, and other public in-kind benefits by {opth other:public(varlist)}, health user fees by {opth userfeesh:ealth(varlist)}, education user fees by {opth userfeese:duc(varlist)}, and other public user fees by {opth userfeeso:ther(varlist)}. Tax and contribution variables may be saved as either positive or negative values, as long as one is used consistently for all tax and contribution variables. The same goes for user fees variables. The variables provided in the {opth health(varlist)}, {opth educ:ation(varlist)}, and {opth other:public(varlist)} options should already be net of co-payments and user fees; we nevertheless include the separate options {opth userfeesh:ealth(varlist)}, {opth userfeese:duc(varlist)}, and {opth userfeeso:ther(varlist)} so that, for example, user fees can be analyzed. {pstd} For results by income group, the cut-offs of these groups can be changed using the {opth cut1(real)} to {opth cut5(real)} options; the default groups are ultra-poor (less than $1.25 per day in purchasing power parity [PPP] adjusted US dollars), extreme poor ($1.25 to $2.50 PPP per day), moderate poor ($2.50 to $4 PPP per day), vulnerable ($4 to $10 PPP per day), middle class ($10 to $50 PPP per day) and wealthy ($50 and more PPP per day). For example, specify {cmd:cut1(1.90)} to change the first cut-off to $1.90 PPP per day (which would cause the lowest group to become less than $1.90 PPP per day, and the second group--if {opth cut2(real)} is not specified so the default second cut-off is maintained--to range from $1.90 to $2.50 PPP). {pstd} Each fiscal interventions sheet using the ranking from one of the CEQ core income concepts, which include market income, market income plus pensions, net market income, gross income, taxable income, disposable income, consumable income, and final income. The variables for these income concepts, which should be expressed in local currency units (preferably {bf:per year} for ease of comparison with totals from national accounts), are indicated using the {opth m:arket(varname)}, {opth mp:luspensions(varname)}, {opth n:etmarket(varname)}, {opth g:ross(varname)}, {opth t:axable(varname)}, {opth d:isposable(varname)}, {opth c:onsumable(varname)}, {opth c:onsumable(varname)}, and {opth f:inal(varname)} options. {pstd} {cmd: ceqfiscal} automatically converts local currency variables to PPP dollars, using the PPP conversion factor given by {opth ppp(real)}, the consumer price index (CPI) of the year of PPP (e.g., 2005 or 2011) given by {opth cpib:ase(real)}, and the CPI of the year of the household survey used in the analysis given by {opth cpis:urvey(real)}. The year of PPP, also called base year, refers to the year of the International Comparison Program (ICP) that is being used, e.g. 2005 or 2011. The survey year refers to the year of the household survey used in the analysis. If the year of PPP is 2005, the PPP conversion factor should be the "2005 PPP conversion factor, private consumption (LCU per international $)" indicator from the World Bank's World Development Indicators (WDI). If the year of PPP is 2011, use the "PPP conversion factor, private consumption (LCU per international $)" indicator from WDI. The PPP conversion factor should convert from year of PPP to year of PPP. In other words, when extracting the PPP conversion factor, it is possible to select any year; DO NOT select the year of the survey, but rather the year that the ICP was conducted to compute PPP conversion factors (e.g., 2005 or 2011). The base year (i.e., year of PPP) CPI, which can also be obtained from WDI, should match the base year chosen for the PPP conversion factor. The survey year CPI should match the year of the household survey. Finally, for the PPP conversion, the user can specify whether the original variables are in local currency units per day ({opt da:ily}), per month ({opt mo:nthly}), or per year ({opt year:ly}, the default assumption). {pstd} If the data set is at the individual level (each observation is an individual), the variable with the identification code of each household (i.e., it takes the same value for all members within a household) should be specified in the {opth hh:id(varname)} option; the {opth hs:ize(varname)} option should not be specified. If the data set is at the household level, the number of members in the household should be specified in {opth hs:ize(varname)}; the {opth hh:id(varname)} option should not be specified. In either case, the weight used should be the household sampling weight and should {it:not} be multiplied by the number of members in the household since the program will do this multiplication automatically in the case of household-level data. {pstd} There are two options for including information about weights and survey sample design for accurate estimates and statistical inference. The sampling weight can be entered using {weight} or {help svyset}. Information about complex stratified sample designs can also be entered using {help svyset} since {cmd:ceqfiscal} automatically uses the information specified using {help svyset}. Alternatively, the primary sampling unit can be entered using the {opth psu(varname)} option and strata can be entered using the {opth s:trata(varname)} option. {pstd} By default, {cmd: ceqfiscal} does not allow income concept or fiscal intervention variables to have missing values: if a household has 0 income for an income concept, receives 0 from a transfer or a subsidy, or pays 0 of a tax, the household should have 0 rather than a missing value. If one of these variables has missing values, the command will produce an error. For flexibility, however, the command includes an {opt ignorem:issing} option that will drop observations with missing values for any of these variables, thus allowing the command to run even if there are missing values. {pstd} Negative incomes are allowed, but a warning is issued for each core income concept that has negative values. This is because various measures are no longer well-behaved when negative values are included (for example, the Gini coefficient, concentration coefficient, or squared poverty gap can exceed 1, and other desirable properties of these measures when incomes are non-negative no longer hold when negative values are allowed). {pstd} Results are automatically exported to the CEQ Master Workbook if {cmd:using} {it:filename} is specifed in the command, where {it:filename} is the Master Workbook. By default, {cmd:ceqfiscal} prints to the sheets titled "E11.X FiscalInterventions" where X indicates the income concept (m, m+p, n, g, t, d, c, f); the user can override the sheet names using the {opt sheetm(string)}, {opt sheetmp(string)}, {opt sheetn(string)}, {opt sheetg(string)}, {opt sheett(string)}, {opt sheetd(string)}, {opt sheetc(string)}, and {opt sheetf(string)} options, respectively. Exporting directly to the Master Workbook requires Stata 13 or newer. The Master Workbook populated with results from {cmd:ceqfiscal} can be automatically opened if the {opt open} option is specified (in this case, {it:filename} cannot have spaces). Results are also saved in matrices available from {cmd:return list}. To produce only a portion of the results, specify only a subset of the income concept options or use {opt nod:ecile}, {opt nog:roup}, {opt noc:entile}, or {opt nob:in}. {title:Examples} {pstd}Locals for PPP conversion (obtained from WDI through the {cmd: wbopendata} command){p_end} {phang} {cmd:. local ppp = 1.5713184 // 2005 Brazilian reais per 2005 $ PPP}{p_end} {phang} {cmd:. local cpi = 95.203354 // CPI for Brazil for 2009}{p_end} {phang} {cmd:. local cpi05 = 79.560051 // CPI for Brazil for 2005}{p_end} {pstd}Individual-level data (each observation is an individual){p_end} {phang} {cmd:. ceqfiscal [pw=w] using C:/Output_Tables.xlsx, hhid(hh_code) psu(psu_var) strata(stra_var) m(ym) mplusp(ymplusp) n(yn) g(yg) t(yt) d(yd) c(yc) f(yf) pens(pensions) dtax(income_tax property_tax) cont(employee_contrib employer_contrib) dtransfer(cct noncontrip_pens unemployment scholarships food_transfers) indtax(vat excise) subsidies(energy_subs) health(basic_health preventative_health inpatient_health) education(daycare preschool primary secondary tertiary) userfeeshealth(user_feesh) userfeeseduc(user_feesed) ppp(`ppp') cpibase(`cpi05') cpisurvey(`cpi') open}{p_end} {pstd}Household-level data (each observation is a household){p_end} {phang} {cmd:. ceqfiscal [pw=w] using C:/Output_Tables.xlsx, hsize(members) psu(psu_var) strata(stra_var) m(ym) mp(ymplusp) n(yn) g(yg) t(yt) d(yd) c(yc) f(yf) pens(pensions) dtax(income_tax property_tax) cont(employee_contrib employer_contrib) dtransfer(cct noncontrip_pens unemployment scholarships food_transfers) indtax(vat excise) subsidies(energy_subs) health(basic_health preventative_health inpatient_health) education(daycare preschool primary secondary tertiary) userfeeshealth(user_feesh) userfeeseduc(user_feesed) ppp(`ppp') cpibase(`cpi05') cpisurvey(`cpi') open}{p_end} {title:Saved results} Pending {title:Author} {p 4 4 2}Sean Higgins, CEQ Institute, sean.higgins@ceqinstitute.org {title:References} {pstd}Commitment to Equity (CEQ) {browse "http://www.commitmentoequity.org":website}.{p_end} {phang} Lustig, N. and S.
