A dynamic model of oligopoly in the coffee export market AgEcon
Karp, Larry S.; Perloff, Jeffrey M..
A linear-quadratic, dynamic feedback oligopoly model that nests various market structures is used to estimate the degree of competitiveness and the adjustment paths of the two largest coffee exporters, Brazil and Colombia. Their estimated behavior is relatively competitive. This subgame perfect dynamic model is-compared to a standard static oligopoly model and the open-loop model (the dynamic generalization of the standard static model). Both classical and Bayesian tests of open-loop and feedback dynamic models are reported.

A Small-Sample Estimator for the Sample-Selection Model AgEcon
Golan, Amos; Moretti, Enrico; Perloff, Jeffrey M..
A semiparametric estimator for evaluating the parameters of data generated under a sample selection process is developed. This estimator is based on the generalized maximum entropy estimator and performs well for small and ill-posed samples. Theoretical and sampling comparisons with parametric and semiparametric estimators are given. This method and standard ones are applied to three small-sample empirical applications of the wage-participation model for female teenage heads of households, immigrants, and Native Americans.

Alternate bearing in Californian pears and avocados AgEcon
Allen, Roy E.; Perloff, Jeffrey M..
This paper develops a test for the presence of alternate bearing and a means of consistently estimating yields for crops whose output varies from year to year for reasons not fully captured by available biological and economic variables. Using these techniques one can better forecast yields than one can using previous methods. This approach is illustrated for the California Bartlett pear and avocado industries.

An information based sample-selection estimation model of agricultural workers' choice between piece-rate and hourly work AgEcon
Golan, Amos; Moretti, Enrico; Perloff, Jeffrey M..
This paper presents a new generalized maximum entropy (GME) approach to estimation of sample-selection models with small data sets, such as are found in many empirical agricultural economic analysis. For small samples, the GME approach produces more stable estimates and has smaller mean square error measures than other well-known estimators such as ordinary least squares, Heckman's two-step method, full-information maximum likelihood, and Ahn and Powell's method. The technique is used to analyze whether hired agricultural workers will work in piece-rate or time-rate jobs and to compare female-male wage differentials for both types of jobs.

An Open-Access Fishery with Rational Expectations AgEcon
Berck, Peter; Perloff, Jeffrey M..
How potential entrants to an open-access fishery form their expectations determines the fishery’s adjustment path to a steady state but not the steady state values themselves. It is well known that, in the standard model with myopic expectations (those based on current values), boats enter the fishery only when the fish stock is greater than its steady state stock. We show that, with rational expectations (perfect foresight), however, boats may enter when the fish stock is much lower than its steady state value if the boat fleet is sufficiently small. This paper contrasts myopic and rational expectations within a general dynamic model of an open-access fishery.

CHINA'S INCOME DISTRIBUTION OVER TIME: REASONS FOR RISING INEQUALITY AgEcon
Wu, Ximing; Perloff, Jeffrey M..
We estimate China's rural, urban and overall income distributions using grouped data from 1985-2001. We show how the distributions evolve as well as examine trends in welfare indices. We find the growing rural-urban income gap and increases in inequality within either sector have been equally responsible for overall inequality growth.

China's Income Distribution over Time: Reasons for Rising Inequality AgEcon
Wu, Ximing; Perloff, Jeffrey M..
We use a new method to estimate China's income distributions using publicly available interval summary statistics from China's largest national household survey. We examine rural, urban, and overall income distributions for each year from 1985-2001. By estimating the entire distributions, we can show how the distributions change directly as well as examine trends in traditional welfare indices such as the Gini. We find that inequality has increased substantially in both rural and urban areas. Using an inter-temporal decomposition of aggregate inequality, we determine that increases in inequality within the rural and urban sectors and the growing gap in rural and urban incomes have been equally responsible for the growth in overall inequality over the last...

Collinearity in Linear Structural Models of Market Power AgEcon

The well-known structural model used to estimate market structure suffers from a severe collinearity problem if the marginal cost and demand equations are linear.

Data Needs for Consumer and Retail Firm Studies AgEcon
Perloff, Jeffrey M.; Denbaly, Mark.
Growing concentration in the retail grocery sector raises new economic questions that are difficult to answer with existing data sources. In part because of concentration in the retail data industry as well the fact that these data are not primarily collected for academic research purposes, currently available grocery-level datasets are extremely expensive, not properly randomized, and lack critical information. We discuss the increase in concentration at the retail level, concentration in data provision, data needs for a number of important research areas, and possible solutions.

Distributing pollution rights in cap-and-trade programs: are outcomes independent of allocation? AgEcon
Fowlie, Meredith; Perloff, Jeffrey M..
According to the Coase theorem, if property rights to pollute are clearly established and emissions permit markets nearly eliminate transaction costs, the permit market equilibrium will be independent of how the permits are initially distributed among …firms. Testing the independence of …firms' permit allocations and emissions is difficult because of endogeneity and omitted variable bias. We exploit the random assignment of …firms to different permit allocation cycles in Southern California's RECLAIM Program to test for a causal relationship between facility-level emissions and initial permit allocations. Our primary …finding is that a null hypothesis of zero effect cannot be rejected.

Do women and minorities earn less due to occupational segregation, lower wages, or fewer hours? AgEcon
Lynch, Lori; Perloff, Jeffrey M..
Using consistently estimated occupational, wage, and hours equations, we calculate earnings differentials by gender, race, and ethnicity. For example, if the market treated women like men, the average women would have earned $133 more per week so that American women would have earned $338 billion more per year. We decompose the earnings differential into wage, hours, and occupational effects. Occupational segregation explains little of the earnings differential for women, but roughly a fifth of the differential for black and Hispanic men. For all groups, within-occupation wage discrimination is responsible for most of the earnings differential.

Dynamic dumping AgEcon
Berck, Peter; Perloff, Jeffrey M..
A low-cost foreign firm lowers its initially high price–dumping if necessary– until it drives the higher cost domestic firms out of business, whereupon it raises its price. At no time, however, does the foreign firm predate (price below its marginal cost). Tariffs, quotas, and other policies that mandate a minimum number of domestic firms do not qualitatively change the price path (high price, low price, and limit price). The optimal tariff in this dynamic analysis is lower than the optimal tariff in a static analysis (to allow consumers to take advantage of the low-price period).

Dynamic oligopoly: estimation and tests of market structure AgEcon
Karp, Larry S.; Perloff, Jeffrey M..
A linear-quadratic dynamic oligopoly model is developed and applied to the world coffee export market. The model nests various market structures using either open-loop or feedback strategies. The theoretical properties of this model are described. For given observed behavior, the assumption of feedback strategies implies a less competitive market structure than open-loop strategies.
