Estimating Heterogeneous Capacity And Capacity Utilization In A Multi-Species Fishery, Ronald G. Felthoven, William C. Horrace, Kurt E. Schnier
Estimating Heterogeneous Capacity And Capacity Utilization In A Multi-Species Fishery, Ronald G. Felthoven, William C. Horrace, Kurt E. Schnier
Economics - All Scholarship
We use a stochastic production frontier model to investigate the presence of heterogeneous production and its impact on fleet capacity and capacity utilization in a multi-species fishery. Furthermore, we propose a new fleet capacity estimate that incorporates complete information on the stochastic differences between each vessel-specific technical efficiency distribution. Results indicate that ignoring heterogeneity in production technologies within a multi-species fishery, as well as the complete distribution of a vessel’s technical efficiency score, may yield erroneous fleet-wide production profiles and estimates of capacity. Furthermore, our new estimate of capacity enables out-of-sample production predictions predicated on either homogeneity or heterogeneity modeling …
Labor Supply With Social Interactions: Econometric Estimates And Their Tax Policy Implications, Andrew Grodner, Thomas J. Kniesner
Labor Supply With Social Interactions: Econometric Estimates And Their Tax Policy Implications, Andrew Grodner, Thomas J. Kniesner

Our research fleshes out econometric details of examining possible social interactions in labor supply. We look for a response of a person's hours worked to hours worked in the labor market reference group, which includes those with similar age, family structure, and location. We identify endogenous spillovers by instrumenting average hours worked in the reference group with hours worked in neighboring reference groups. Estimates of the canonical labor supply model indicate positive economically important spillovers for adult men. The estimated total wage elasticity of labor supply is 0.22, where 0.08 is the exogenous wage change effect and 0.14 is the …
Does The Quality Of Training Programs Matter? Evidence From Bidding Processes Data, Alberto Chong, Jose Galdo
Does The Quality Of Training Programs Matter? Evidence From Bidding Processes Data, Alberto Chong, Jose Galdo

We estimate the effect of training quality on earnings using a Peruvian program, which targets disadvantaged youths. The identification of causal effects is possible because of two attractive features in the data. First, selection of training courses is based on public bidding processes that assign standardized scores to multiple proxies for quality. Second, the evaluation framework allows for the identification and comparison of individuals in treatment and comparison groups six, 12, and 18 months after the program. Using difference-indifferences kernel matching methods, we find that individuals attending high-quality training courses have higher average and marginal treatment impacts. External validity was …
Identifying Technically Efficient Fishing Vessels: A Non-Empty, Minimal Subset Approach, William C. Horrace, Kurt E. Schnier, Alfonso Flores-Lagunes
Identifying Technically Efficient Fishing Vessels: A Non-Empty, Minimal Subset Approach, William C. Horrace, Kurt E. Schnier, Alfonso Flores-Lagunes

There is a growing resource economics literature, concerning the estimation of the technical efficiency of fishing vessels utilizing the stochastic frontier model. In these models, vessel output is regressed on a linear function of vessel inputs and a random composed error. Using parametric assumptions on the regression residual, estimates of vessel technical efficiency are calculated as the mean of a truncated normal distribution and are often reported in a rank statistic as a measure of a captain’s skill and used to estimate excess capacity within fisheries. We demonstrate analytically that these measures are potentially flawed, and extend the results of …
Estimating Heterogeneous Production In Fisheries, Kurt E. Schnier, Christopher M. Anderson, William C. Horrace
Estimating Heterogeneous Production In Fisheries, Kurt E. Schnier, Christopher M. Anderson, William C. Horrace

Stochastic production frontier models are used extensively in the agricultural and resource economics literature to estimate production functions and technical efficiency, as well as to guide policy. Traditionally these models assume that each agent’s production can be specified as a representative, homogeneous function. This paper proposes the synthesis of a latent class regression and an agricultural production frontier model to estimate technical efficiency while allowing for the possibility of production heterogeneity. We use this model to estimate a latent class production function and efficiency measures for vessels in the Northeast Atlantic herring fishery. Our results suggest that traditional measures of …
Inter-Industry Gender Wage Gaps By Knowledge Intensity: Discrimination And Technology In Korea, William C. Horrace, Beyza P. Ural, Jin Hwa Jung
Inter-Industry Gender Wage Gaps By Knowledge Intensity: Discrimination And Technology In Korea, William C. Horrace, Beyza P. Ural, Jin Hwa Jung
Economics - All Scholarship
A new gender wage gap decomposition methodology is introduced that does not suffer from the identification problem caused by unobserved non-discriminatory wage structure. The methodology is used to measure the relative size of Korean gender wage gaps from 1994 to 2000 across industries, differentiated by industrial knowledge intensity, where knowledge intensity is the extent to which industries produce or employ high-technology products. Korea represents an important case study, since it possesses one of the fastest growing knowledge-intensive economies, among industrialized countries. Empirical results indicate that over this period, discrimination (the unexplained portion of the gender wage gaps) in Korea was …
