Abstract:
We conducted a standard gravity exercise using worldwide disaggregated trade data to shed light on the influence of the spread of digital technologies on network trade. We found that growing investment in industrial robots in relatively lagging countries, together with imported digitally deliverable services, is enhancing bilateral network trade flows in East Asia, but not necessarily in other parts of the world. This suggests that exploring complementarities between machines and human resources in production blocks supported by better service-link connectivity may allow newly developed economies to retain and expand the international division of labour.

Abstract:
Using job transition data from Argentina’s Household Survey, we document the extent to which human capital is specific to occupations and activities. Based on workers’ propensity to move between occupations/industries, we build Occupation and Industry Spaces to illustrate job similarities, and we compute an occupation and industry similarity measures that, in turn, we use to explain wage transition dynamics. We show that our similarity measures influence positively post-transition wages. Inasmuch as wages capture a worker's marginal productivity and this productivity reflects the degree to which a worker matches the job’s skill demand, our results indicate that a worker's human capital is specific to both occupation and activity: closer occupations share similar skill demands and task composition (in other words, demand similar workers) and imply a smaller human capital loss in the event of a transition.

Abstract:
This paper examines the role of industrial policy on firms’ productivity, using 3 years of panel data on Thai manufacturing as a case study. A range of industrial policy tools is defined – tariff measures, subsidies, and investment incentives through the Board of Investment (BOI) – which are the main tools used in Thailand. The effect on firm productivity of partial trade liberalisation undertaken through free trade agreements (FTAs) signed between Thailand and its trading partners is also examined. The key finding is that trade openness and research and development (R&D) are more crucial in fostering firms’ productivity than industrial policies. This is especially true for the narrow definition of industrial policy focusing on trade policy protection, measured by the effective rate of protection. In addition, the FTA-led trade liberalisation effect fails to add substantial competitive pressure and make firms improve productivity. Our results show that sectors benefiting from subsidies show noticeably lower productivity than others. Our study found weak support for investment promotion policy through the BOI, even when the domestic competitive environment is considered in our analysis.

Abstract:
We present the first study of the high school-to-work transition for American Millennial males and females. Using data from the PSID Transition to Adulthood from 2005-2011, we estimate the Burdett and Mortensen (1998) model and study changes between Generation X and Millennials. We find convergence in racial differences in transition patterns across the generations and in gender earnings by the Great Recession. These patterns are driven by a large decline in search efficiencies for white males. Finally, we show the labor market deteriorated for high school graduates prior to, with a further decline during, the Great Recession.

45. Prices, Profits, Proxies, and Production

Abstract:
This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent rendering standard approaches inapplicable. Instead, we require observation of profits or other optimizing-values such as costs or revenues, and either prices or price proxies of flexibly chosen variables. We extend classical duality results for price-taking firms to a setup with discrete heterogeneity, endogeneity, and limited variation in possibly latent prices. Finally, we show that convergence results for nonparametric estimators may be directly converted to convergence results for production sets.

46. Optimal Contracting with Altruistic Agents: A Structural Model of Medicare Payments for Dialysis Drugs

Abstract:
We study physician agency and optimal payment policy in the context of an expensive medication used in dialysis care. Using Medicare claims data we estimate a structural model of treatment decisions, in which physicians differ in their altruism and marginal costs, and this heterogeneity is unobservable to the government. In a novel application of nonlinear pricing methods, we theoretically characterize the optimal unrestricted contract in this screening environment with multidimensional heterogeneity. We combine these results with the estimated model to construct the optimal contract and simulate counterfactual outcomes. The optimal contract is a flexible fee-for-service contract, which pays for reported treatments but uses variable marginal payments instead of constant reimbursement rates, resulting in substantial health improvements and reductions in costs. Our structural approach also yields important qualitative findings, such as rejecting the optimality of any linear contract, and may be employed more broadly to analyze a variety of applications.

47. Child Skill Production: Accounting for Parental and Market-Based Time and Goods Investments

Abstract:
This paper studies the multidimensional nature of investments in children within a dynamic framework. In particular, we examine the roles of parental time investments, purchased home goods/services inputs, and market-based child care services. We first document strong increases in total investment expenditures by maternal education; yet expenditure shares, which skew heavily towards parental time, vary little with parental schooling. Second, we develop an intergenerational lifecycle model with multiple child investment inputs to study these patterns and the impacts of policies that alter the prices of different inputs. We analytically characterize investment behavior, focusing on the substitutability of different investment inputs and the way parental skills affect the productivity of family-based inputs. Third, we develop an estimation strategy that exploits intratemporal optimality conditions based on relative demand to estimate substitutability between inputs, the relative productivity of different inputs, and the role played by parental education. This approach requires no assumptions about the dynamics of skill investment, preferences, or credit markets. We also account for mismeasured inputs and wages, as well as unobserved heterogeneity in parenting skills. We further show how noisy measures of child achievement (measured several years apart) can also be incorporated in a generalized method of moments approach to additionally identify the dynamics of skill accumulation. Fourth, we use data from the Child Development Supplement of the Panel Study of Income Dynamics to estimate the skill production technology for children ages 12 and younger. Our estimates suggest complementarity between parental time and home goods/services inputs as well as between these family-based inputs and market-based child care, with elasticities of substitution ranging from 0.2 to 0.5. We find no systematic effects of parental education on the relative productivity of parental time and other home inputs. Finally, we use counterfactual simulations to explore the extent and sources of variation in investments across families, as well as investment responses to changes in input prices. We find that variation in prices explains 48% of the overall variance in investment expenditures, and differences in wages explain more than half of the investment expenditure gap between college-educated and non-college-educated parents. We further show that accounting for the degree of input complementarity implied by our estimates has important implications for the responses of individual inputs to any price change and for the responses in total investments and skill accumulation to large (but not small) price changes.

48. Returns to Skill and the Evolution of Skills for Older Men

Abstract:
This paper shows that repeated cross-section data with multiple skill measures (one continuous and repeated) available each period are sufficient to nonparametrically identify the evolution of skill returns and cross-sectional skill distributions. With panel data and the same available measurements, the dynamics of skills can also be identified. Our identification strategy motivates a multi-step nonparametric estimation strategy. We further show that if any continuous repeated measurement is shown to be linear in skills, a much simpler GMM estimator can be used. Using HRS data on men ages 52+ from 1996-2016, we show that one of the available (continuous and repeated) skill measures is linear in skills and implement our GMM estimation approach. Our estimates suggest that the returns to skill were fairly stable from the mid-1990s to the Great Recession, rising thereafter. We document considerable differences in skills and lifecycle skill profiles over ages 52–70 across cohorts, with more recent cohorts possessing lower skills in their mid-50s but experiencing much weaker skill declines with age. We also document skill differences by education and race, which are stable across ages and explain roughly one-third and one-half, respectively, of the corresponding differences in wages. We observe substantial differences in skills for men in their mid-50s choosing to retire at different ages, but no clear evidence of sharp declines in skills surrounding retirement ages. Finally, we show that individual fixed effects account for more than a third of all skill variation at age 60, with considerable persistence in year-to-year skill innovations.

49. The EITC and Maternal Time Use: More Time Working and Less Time with Kids?

Abstract:
Parents spend considerable time and resources investing in their children's development. Given evidence that the Earned Income Tax Credit (EITC) aects maternal labor supply, we investigate how the EITC aects a broad array of time-use activities, focusing on the amount and nature of time spent with children. Using 2003-2018 time-use data, we nd that federal and state EITC expansions increase maternal work time, which reduces time devoted to home production, leisure, and time with children. However, for children of all ages, almost none of the reduction comes from time devoted to investment activities, such as active learning and development activities.

Abstract:
While a large literature is interested in the relationship between family and labor supply outcomes, little is known about the expectations of these objects at earlier stages. We examine these expectations, taking advantage of unique data from the Berea Panel Study. In addition to characterizing expectations, starting during college, the data details outcomes for ten years after graduation. Methodological contributions come from approaches to validate quality of survey expectations data and the recognition that expectations data, along with longitudinal data, can potentially help address endogeneity issues arising in the estimation of the causal effect of family on labor supply.
