Estimating the effect of monopsony power on elasticity estimates

Love and Shumway (1994) developed a nonparametric deterministic test for monopsony market power using a normalized quadratic restricted cost function with one input for which the firm has potential market power. This research examines monopsony power using Lau’s Hessian identity relationships based on the empirical properties of duality theory. Lau’s Hessian identity shows the Hessian matrices are equal under pure competition using an unrestricted profit function, restricted profit function and production function approach. We examine how market power changes in the monopsony case using Lau’s Hessian identity relationships. Results show that there is a difference between the unrestricted and restricted profit function results under monopsony power. The important implication is that if an input or output is potentially in a market subject to market power, that input or output should be modelled as a fixed input or output to correctly recover the underlying technology.     

A Random Parameter Model with Onsite Sampling for Recreation Site Choice: An Application to Southern California Shoreline Sportfishing

Estimation of consistent parameter estimates for recreational demand models faces challenges arising from the choice-based nature of the data collected primarily for resource management purposes. As an alternative to randomized respondent-based sampling, choice-based onsite sampling can provide information on actual choices made by a subset of the population where participation has a low incidence. While the literature has shown that under specific restrictions the estimation of choice models from onsite sampling data yields unbiased fixed parameter estimates for the conditional logit model, this result does not carry over to estimation of the random parameter logit model. We propose an estimator for the unbiased estimation of the random parameter model using choice-based data; our estimator uses weights based on information about the level of sampling effort. An empirical application of the standard and weighted discrete choice RUM models to onsite sample data on recreational fishing illustrates the advantages of the proposed estimator. The estimation results indicate the compensating variation associated with an decrease, or increase, of 50 % in expected catch rates for a recreational shoreline sportfishing trip to a man-made structure in southern California is $$-{\$}2.80$$ or $${\$}3.54$$ per trip, respectively.     

Asymptotic Properties Of The Estimator Of The Long-Run Coefficient In A Dynamic Model With Integrated Regressors And Serially Correlated Errors

In this paper we examine the asymptotic properties of the estimator of the long-run coefficient (LRC) in a dynamic regression model with integrated regressors and serially correlated errors. We show that the OLS estimators of the regression coefficients are inconsistent but the OLS-based estimator of the LRC is superconsistent. Furthermore, we propose an alternative consistent estimator of the LRC, compare the two estimators through a Monte Carlo experiment, and find that the proposed estimator is MSE-superior to the OLS-based estimator.     

Dynamic analysis of patent policy in an endogenous growth model

In this paper, we explore the dynamic properties of an endogenous growth model with finite patent length. We show that there exists a unique equilibrium growth path and that this path exhibits damped oscillations in contrast to the equilibrium path of an endogenous growth model with infinite patent length. We also examine the effects of patent policy on social welfare and show that infinite patent length does not maximize social welfare. Furthermore, we show that, in a growth model that does not exhibit scale effects, a finite patent length maximizes social welfare on the balanced growth path.     

Can a Regional Trade Agreement Benefit a Nonmember Country without Compensating It?

RTAs are generally formed without any tariff concessions or transfers to nonmember countries. Can such an RTA benefit nonmembers' welfare? In a two‐good three‐country competitive equilibrium model in the absence of an entrepôt, an RTA without concessions to a nonmember will hurt nonmembers' welfare when goods are normal. If one of the member countries is an entrepôt, however, it definitely improves nonmembers' welfare. In a three‐good three‐country model, an RTA without concessions damages the nonmember's welfare, provided that all the goods are normal and substitutes, and that initial tariff levels are small.     

How enterprise strategies are related to innovation and productivity change: an empirical study of Japanese manufacturing firms

This study analyzes the total factor productivity of 1067 Japanese manufacturing firms. In production estimation, we employ the directional distance function and Luenberger productivity indicator. Research and development strategy survey data are used to analyze the determinant factors related to improvements in innovation and productivity. Our results indicate that increasing technology and knowledge through a ‘black box’ process is related to an increase in productivity. Furthermore, the protection and management of production knowledge and expertise is a valid method of increasing global technical change.
