INFLATION INEQUALITY IN THE UNITED STATES

Different spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation faced by different households. In this paper we measure the degree of inequality in inflation across U.S. households for the period 1987–2000. The broad picture that emerges from our results is that over our whole sample period there are substantial differences in the inflation experiences across U.S. households. We find that the cost of living increases were generally higher for the elderly, in large part because of their health care expenditures, and that the cost of living of poor households is most sensitive to the, historically large, fluctuations in gasoline prices. Still, when looking at the whole population, we find that individual households that are confronted with high inflation in one year do not generally face high inflation in the subsequent year as well.     

Regulatory compliance,information disclosure and peer effects: evidence from the Mexican gasoline market

Policy makers and regulators are increasingly interested in the use of information disclosure as a regulatory instrument to improve firms’ behavior. However, little has been done using micro-level data to investigate whether information provision may trigger peer influence among firms that affects their compliance behavior. Using station-level inspection verification data from the Mexican gasoline market, this paper examines whether gas stations react to peers’ performance to adjust their own compliance decisions. The information disclosure policy assigned each inspected gas station with green, yellow, or red colors to indicate the status of compliance, minor violation, and severe violation, respectively. We find strong evidence of peer influence triggered by information spillover. The probability of being in compliance increases as the number of “green” peers increases. We use both municipalities and postal codes as geographic boundaries to define potential peers, and find similar results. Our findings also suggest that the magnitude of peer effects varies across municipalities: the effects appear to be greater in wealthier, more educated communities.     

Allocative inefficiency and sectoral allocation of labor: Evidence from U.S. agriculture

Are productivity differences across producers in an industry a good indicator of allocative inefficiency? If so, what are the welfare consequences of reallocating labor from lesser to more productive producers? This paper addresses these questions in the context of factor specificity, which generates endogenous distribution of total factor productivity across producers, and reallocation of labor across sectors, as well as within a sector. The paper builds a multi-sector, multi-region general equilibrium model with land as a region-specific factor, and calibrates it using state-level U.S. data from 1960 to 2004, a period with considerable reallocation of labor out of agriculture. The results show that large and persistent differences in agricultural productivity across U.S. states are consistent with factor specificity due to geoclimatic conditions and do not correspond to economically significant allocative inefficiencies.     

WORK HISTORIES AND LIFETIME UNEMPLOYMENT

A long-standing question in economics is how important unobserved differences across workers are for explaining unemployment. I revisit this topic using variation in lifetime unemployment across workers in U.S. data. A comparison of workers often unemployed with the rest shows that although differences in job-finding rates increase over the course of a career, differences in job-separation rates are large right from the start. I develop a directed search model with symmetric unobserved heterogeneity, in which agents learn workers' types from their labor market histories, to rationalize these findings. The model cannot match the data if unobserved heterogeneity is neglected.     

The impact of the market transparency unit for fuels on gasoline prices in Germany

Increasing horizontal as well as vertical transparency in oligopolistic markets can be advantageous for consumers, due to reduced search costs. However, market transparency can also affect incentives to deviate from collusive agreements and the punishment by rival firms in the market. Using a panel of 27 European countries, we analyse the impact of increased market transparency via the introduction of a market transparency unit for fuels in Germany. Applying a difference-in-differences approach, we find evidence that both gasoline and diesel prices have increased. While consumers may be better off using a retail price app for fuels, gas stations are also able to compare prices at almost no cost.     

Price response,information, and asymmetry of price dispersion

In this study, we examine how differently gasoline prices in 25 regions of Seoul, Korea respond to asymmetric information between retailers and consumers. We estimate the region-specific likelihood that retailers engage in price undercutting under asymmetric information and investigate inter-regional differences. We find that in response to increases in wholesale price, regions with a high likelihood of price undercutting experience intensified gas station price competition while dispersions of price and markups tend to decrease more in response to cost shocks. Understanding the geographical dispersion of retailers’ price responses to information frictions and search intensity is crucial to lowering information barriers across regions and redistributing profit among market participants.     

Optimal taxation and cross-price effects on labor supply: Estimates of the optimal gas tax

This study estimates parameters necessary to calculate the optimal second-best gasoline tax, most notably the cross-price elasticity between gasoline and leisure. Prior theoretical work indicates the importance of this elasticity, but despite this, almost none of the prior studies of commodity taxation (and none of the studies on second-best environmental regulation) actually estimate it. Using household data, we find that gasoline is a relative complement to leisure, and thus that the optimal gasoline tax is significantly higher than marginal damages-the opposite of the result suggested by the bulk of the prior literature. Indeed, even if there were no externalities at all associated with gasoline, the optimal tax rate would still be almost equal to the average gas tax rate in the U.S. Following this approach to estimate cross-price elasticities with leisure could strongly influence estimates of optimal rates for other important commodity or pollution taxes.     

Networks or neighborhoods? Correlations in the use of publicly-funded maternity care in California

This study focuses on “network effects” in the utilization of publicly-funded prenatal care using Vital Statistics data from California for 1989-2000. Networks are defined using 5-digit zip codes and a woman's racial or ethnic group. Like others, we find evidence that the use of public programs is highly correlated within groups defined using race/ethnicity and neighborhoods. These correlations persist even when we control for many unobserved characteristics by including zip code-year fixed effects, and when we focus on the interaction between own group behavior and measures of the potential for contacts with other members of the group (“contact availability”). However, the richness of our data allows us to go further and to conduct several tests of one important hypothesis about networks: that the estimated effects represent information sharing within groups. The results cast doubt on the idea that the observed correlations can be interpreted as evidence of information sharing. In particular, we find estimated effects to be as large or larger among women who have previously used the program as among first-time users.     

THE IMPACT OF DECONTROL ON GASOLINE WHOLESALERS AND RETAILERS

Since decontrol of the U.S. gasoline market in January 1981, substantial changes in operations of gasoline retailers (dealers) and wholesalers (jobbers) have occurred. This paper analyzes decontrols impact on the operations of these two classes of firms. A primary conclusion is that removing regulations allowed dealers to profit by cutting prices and margins for self-service gasoline, while increasing prices and margins for full-service gasoline. In addition, decontrol resulted in lower jobber margins and profitability, which in turn caused a substantial number of jobbers to exit from the market. Overall, removal of the regulations allowed operational changes which were consistent with emerging technology and consumer demands, but which had been constrained by a decade of pervasive federal regulation of the U.S. gasoline market. Thus, decontrol fostered greater economic efficiency in the marketing of gasoline, which contributed to lower gasoline prices during a time of rising gasoline taxes and increasing general inflation.     

FAMILY INCOME,AGE, AND SIZE OF UNIT: SELECTED INTERNATIONAL COMPARISONS*

Two aspects of the relationship between family unit income and the age of the head of the family unit are examined in this exploratory paper. First, in connection with the recent discussion in the U.S. about the “fair” level of income of the aged population, the economic well-being of various age of head groups is examined for the U.S., Canada, Norway, and Israel. Problems inherent in comparing income distributions across countries are described briefly, and the sensitivity of the estimates to definitional differences is discussed. Relative incomes of the different age groups are then compared within and between countries. Relative mean incomes, relative median incomes, relative mean incomes adjusted for size of unit in alternative ways, distributions of age groups among income quintiles, and relative income shares within age groups are compared. The focus is on aged units. It is found that, using these crude measures, aged units in the U.S. are roughly as well off relative to the other age groups as aged groups in the other countries examined. In the second section of the paper, a U.S. microdata file is reweighted to be consistent with the distributions by age of head of Norway and Canada. Relative income shares of quintiles are computed before and after reweighting and compared with the shares for Norway and Canada. The reweighting to Norway's age distribution increased differences in relative income shares between the two countries; the reweighting to Canada's age distribution slightly decreased differences.     

Job search and unemployment insurance: New evidence from time use data

This paper provides new evidence on job search intensity of the unemployed in the U.S., modeling job search intensity as time allocated to job search activities. The major findings are: 1) the average U.S. unemployed worker devotes about 41 min to job search on weekdays, which is substantially more than their European counterparts; 2) workers who expect to be recalled by their previous employer search substantially less than the average unemployed worker; 3) across the 50 states and D.C., job search is inversely related to the generosity of unemployment benefits, with an elasticity between ?1.6 and ?2.2; 4) job search intensity for those eligible for Unemployment Insurance (UI) increases prior to benefit exhaustion; and 5) time devoted to job search is fairly constant regardless of unemployment duration for those who are ineligible for UI.     

INTERNATIONAL DEVIATIONS FROM THE LAW OF ONE PRICE: THE ROLE OF SEARCH FRICTIONS AND MARKET SHARE*

This article examines the size and persistence of international deviations from the law of one price in an industry with search frictions. Cost differences lead foreign and domestic firms to price differently within countries. When local firms are more common in each country, there are large and persistent price differences across countries. Large and persistent changes in international relative costs lead to large and persistent changes in international relative prices. Dynamic considerations imply that the amount of a cost shock firms pass through to prices is U‐shaped in the market share of firms receiving the shock.     

Fertility Decisions and Gender Differences in Labor Turnover, Employment, and Wages

A striking observation of the U.S. and other labor markets is the weak position of women in terms of job attachment, employment, and earnings relative to men. We develop a model of fertility and labor market decisions to study the impact of fertility on gender differences in labor turnover, employment, and wages. In our framework, individuals search for jobs and accumulate general (experience) and specific (tenure) human capital when they work. They can also increase their wage by moving to a job of higher quality. Labor market decisions (e.g., job acceptance and job mobility) may differ across genders: females that give birth may decide to interrupt their labor market attachment in order to enjoy the value of staying at home with their children. The model economy is successfully calibrated to match aggregate statistics in terms of fertility, employment, and wages. We find that fertility decisions generate important gender differences in turnover rates, with long lasting effects in employment and wages. These differences in labor turnover account for almost all the U.S. gender wage gap that is attributed to labor market experience by Blau and Kahn (2000, Journal of Labor Economics15(1), 1–42). The model also implies a very small role of tenure capital in accounting for wage differences between males and females (gender gap), and between females with and without children (family gap).

COMPARATIVE WELL-BEING OF CHILDREN AND ELDERLY

This paper compares the economic well-being of children and the elderly to each other in the United States and across six industrialized countries. Using the Luxembourg Income Study database, we find that U.S. children–whose economic status is measured by their family income–are generally worse off than U.S. elderly in terms of both poverty and adjusted mean income. Moreover, U.S. children are worse off in terms of higher poverty rates than are the children in any of the other countries studied. The paper presents a variety of explanations for these differences.     

Trade responses to geographic frictions: A decomposition using micro-data

A large literature has shown that geographic frictions reduce trade, but has not clarified precisely why. In this paper, we provide some insight into why such frictions matter by examining what parts of trade these frictions reduce most. Using data that track manufacturers’ shipments within the US on an exceptionally fine grid, we find that the pattern of shipments is extremely localized. Shipments within 5-digit zip codes, which have a median radius of just 4 miles, are 3 times larger than shipments outside the zip code. We decompose aggregate shipments into extensive and intensive margins, and show that distance and other frictions reduce aggregate trade values primarily by reducing the number of commodities shipped and the number of establishments shipping. Extensive margins are particularly important over very short distances. We examine trade in intermediate goods as an explanation for highly localized shipments and the dominant role of the extensive margin and find evidence consistent with this hypothesis. In another significant finding, we find no evidence of state-level home bias when distances are measured precisely and trade is observed over a very fine grid.     

Are Americans Really Less Happy with Their Incomes?

Recent economic research on international comparisons of subjective well‐being suffers from several important biases due to the potential incomparability of response scales within and across countries. In this paper we concentrate on self‐reported satisfaction with income in two countries: the Netherlands and the U.S. The comparability problem is addressed by using anchoring vignettes. We find that in the raw data, Americans appear decidedly less satisfied with their income than the Dutch. It turns out however that after response scale adjustment based on vignettes, the distribution of satisfaction in the two countries is essentially identical. In addition, we find that the within‐country cross‐sectional effect of income on satisfaction—a key parameter in the recent debate in the economic literature—is significantly underestimated, especially in the U.S., when differences in response scales are not taken into account.     

The effect of entry restrictions on price: evidence from the retail gasoline market

I exploit a change in Spanish regulations to test the effect of the relaxation of entry restrictions on the equilibrium retail price of diesel. In February 2013, a Central Government reform permitted gasoline stations to operate in industrial and commercial areas. Over the following 2-year period, this deregulation led to a high number of new market entrants in these newly designated free entry areas. By isolating markets exposed to entry and markets unaffected by new entrants, and adopting a difference-in-difference approach, results show that gasoline stations exposed to a new market entrant within a one-mile radius lower their prices by an average 1.04%. This result is significant, representing almost one fifth of the average retail margin. Additionally, the results show that the reduction in the equilibrium price is caused by the first market entrant and that the effect decreases over time.     

Do immigrants delay retirement and social security claiming?

ABSTRACT

We use data from the Health and Retirement Study (HRS) to examine how immigrants’ retirement and Social Security claiming patterns compare to those of natives. We find that immigrants retire and claim Social Security at older ages than natives, an effect that is similar across immigrant ethnic groups and more pronounced among immigrants who arrived in the U.S. after age 40. We discuss and explore possible mechanisms for these differences. Hazard models suggests that these differences arise because immigrants have lower retirement and claiming hazard rates in their early 60s. We do not find evidence of an increase in the rate at which immigrants move abroad or exit the survey, compared to U.S. natives, in their late 50s through 60s, a finding that is consistent with immigrants retiring in the U.S. rather than abroad. These results are important given the rising share of older immigrants living in the U.S., and they have implications for the impact of immigration on government finances as well as the retirement security of an important subgroup of the population.     

Post‐secondary attendance by parental income in the U.S. and Canada: Do financial aid policies explain the differences?

We examine the extent to which tuition and needs‐based aid policies explain important differences in the relationship between family income and post‐secondary attendance relationships between Canada and the U.S. Using data from recent cohorts, we estimate substantially smaller attendance gaps by parental income in Canada relative to the U.S., even after controlling for family background, cognitive achievement, and local‐residence fixed effects. We next document that U.S. public tuition and financial aid policies are actually more generous to low‐income youth than are Canadian policies. Equalizing these policies across Canada and the U.S. would likely lead to a greater difference in income‐attendance gradients.     

The effect of the tax reform act of 1986 on the location of assets in financial services firms

This paper examines the effects of the Tax Reform Act of 1986 on the international location decisions of U.S. financial services firms. The Act included rule changes that made it substantially more difficult for U.S. firms to defer U.S. taxes on overseas financial services income held in low-tax jurisdictions. We use information from the tax returns of U.S. corporations to examine how local taxes affect the allocation of financial assets held abroad by financial services firms. We find that, before the Act, the location of reported assets in financial subsidiaries was responsive to differences in host country tax rates across jurisdictions. However, after the Act, differences in host country tax rates no longer explain the distribution of assets held in financial services subsidiaries abroad. Our results suggest that the tightening of the anti-deferral provisions applicable to financial services companies has been successful in diminishing the effect of host country income taxes on asset location decisions.
