Dynamics and equilibrium in a structural model of wide‐body commercial aircraft markets

This paper develops and estimates a dynamic equilibrium model of the market for new and used commercial aircraft. The model is estimated by maximum simulated likelihood using data on wide‐body aircraft owners and prices for transactions occurring 1978‐1997. The importance of explicitly modeling dynamics and equilibrium in new and used markets for durable goods is illustrated in two counterfactual experiments. Estimates of the structural model are used to show that implementing an investment tax credit not only increases demand for new wide‐body aircraft by the airlines that receive the tax credit, but also increases the number of new wide‐body aircraft owned by airlines not directly affected by the policy. Further, the model indicates that a policy which improves the efficiency of secondary markets for used wide‐body aircraft will also stimulate demand for new wide‐body aircraft.

Parent country nationals or local nationals for executive positions in foreign affiliates: An empirical study of Japanese affiliates in Korea

This study examines how the host country experience of Japanese multinational corporations (MNCs) affects their staffing policies for executive manager positions at foreign affiliates. Hypotheses on executive staffing policies for foreign affiliates are tested using survey data collected from 103 Japanese affiliates in Korea. Findings show that the level of global integration and the degree of centralization of decision-making positively affect an assignment of parent country nationals as executive managers of foreign affiliates. We further find that foreign affiliates’ experience in a host country moderates the effects of both global integration and centralization on staffing decisions for the affiliates.

Residential development in an open city

This paper investigates the residential development process using a dynamic model of an open city. The model is used to analyze how the density and timing of development at various sites respond to changes in exogenous trajectories and functions. In particular, the impact of income and equilibrium utility trajectory variations as well as transportation and construction cost changes are evaluated for the general model with no specific functional forms assumed. Sufficient conditions for predicted responses are derived and interpreted.     

On a Morgenstern-type bivariate gamma distribution

Summary In this paper a Morgenstern-type bivariate gamma distribution has been studied. Its moment generating function has been derived. The distribution of the product and quotient are derived in terms of the modified Bessel function. The results for the independent case follow as special cases. Further the regression function has been analysed, in terms of its deviation from linear regression function.This research was initiated while the first author was a U.N. Consultant under the Statistical Training Program for Africa, visiting the University of Ghana.     

A methodology for the assessment of ridesharing program benefits and impacts

Due to the increased cost and decreased availability of energy, many cities are developing experimental ridesharing programs. The evaluation of such public transportation programs often involves some form of benefit/cost analysis. In this paper we review a methodology proposed by Wagner for calculating ridesharing program benefits. We propose a modification for calculating vehicle-miles reduction and suggest a survey instrument for collecting the appropriate data. In addition, we present a surrogate measure which is simpler to compute and allows sensitivity analysis for incorporating certain intangible factors. Data from a survey conducted in the Greater Cincinnati area is used to illustrate the calculations. The results can be useful in evaluating other ridesharing programs.     

Felony case scheduling policies and continuances: A simulation study

The criminal justice system consists of interacting parts and represents a dynamic process through which the accused moves in stages. This study focuses on felony criminal offenses and the court stage of the judicial process. Specifically this study examines and evaluates utilization of the courtrooms of a legal system under pre-trial policy considerations governing case flow, and identifies problem areas of under-capacity, or bottlenecks. The model presented utilizes simulation as a means of describing the system, and conducting alternative (scheduling) policy requirements. The results of the study reveal that due process can be achieved while minimizing interference with those who want a “speedy trial”.     

Corporate merger and collective bargaining in the UK

Corporate merger since the war has transformed the private sector of the economy in Britain. This has had significant effects on collective bargaining arrangements and outcomes. In this article the authors review these effects and consider their implications for trade union organisation.     

Regression with errors in variables: estimators based on third order moments

In this paper consistent and, in a well–defined sense, optimal moment–estimators of the regression coefficient in a simple regression model with errors in variables are derived. The asymptotic variance and other asymptotic properties of these estimators are given. As is known for a long time, serious estimation problems exist in this model. There are two ways out of this problem: using either additional assumptions or additional information in the data. A lot of attention has been paid to the use of additional assumptions. However, quite often this leads to rather unrealistic models. In this paper we use additional information in the data. That means here that, besides first and second order moments, third order moments are formulated as functions of the model parameters. Besides theoretical derivations a small study with generated data is discussed. This study shows that for samples larger than 50 the estimates we consider behave nicely.
