Evidence on learning in coordination games

This paper reports an experiment designed to detect the influence of strategic uncertainty on behavior in order statistic coordination games, which arise when a player’s best response is an order statistic of the cohort’s action combination. Unlike previous experiments using order statistic coordination games, the new experiment holds the payoff function constant and only changes cohort size and order statistic.

Selective penalization of polluters: an inf-convolution approach

Summary. We consider an asymmetric polluting oligopoly. We demonstrate that optimal tax rates per unit of emission are not the same for all firms. We call this property selective penalization. Our Optimal Distortion Theorem states that the efficient tax structure requires that high cost firms pay a higher tax rate. Our Pro-concentration Motive Theorem states that optimal taxes increase the concentration of the industry, as measured by the Herfindahl index. Our Magnification Effect indicates that the variance of marginal costs is magnified by a factor which depends on the marginal cost of public funds.JEL Classification Numbers: Q20, D60, D63.We wish to thank Peter Neary, Kim Long, Raymond Riezman and a referee for very helpful comments.

Endogenous Trade Policies in a Developing Economy

This paper examines the formation of trade policy for a small open developing economy where lobbying activities may be carried out to influence policy‐making decisions. The paper presents a three‐sector economy in which the manufacturing sector can lobby policymakers for favorable policies. Under some plausible conditions, it is demonstrated that lobbying activities carried out by the owners of the specific factor in the manufacturing sector would secure a protectionist trade policy through either an import tariff or an export subsidy. The government also imposes a consumption tax on agricultural products, which further strengthens the protectionist measure applied to the manufacturing sector. In general equilibrium, there will be a movement of labor to the manufacturing sector, an output expansion in the manufacturing sector, and an output contraction in the agricultural sector, exactly as suggested by factual evidence.     

Explicit tests of contingent claims models of mortgage default

This paper provides explicit and powerful tests of contingent claims approaches to modeling mortgage default. We investigate a model of frictionless default (i.e., one in which transactions costs, reputation costs, and moving costs play no role) and analyze its implications-the relationship between equity and default, the timing of default, its dependence upon initial conditions, and the severity of losses. Absent transactions costs and other market imperfections, economic theory makes well-defined predictions about these various outcomes.The empirical analysis is based upon two particularly rich bodies of micro data: one indicating the default and loss experience of all mortgages purchased by the Federal Home Mortgage Corporation (Freddie Mac), and a large sample of all repeat sales of single family houses whose mortgages were purchased by Freddie Mac since 1976.     

Using the optimization algorithm to evaluate and predict the business performance of logistics companies–a case study in Vietnam

ABSTRACT

In the current market economy, it is important to evaluate and forecast the situation and business performance of enterprises to provide the necessary information for managers to plan for future use of resources. This study aims to evaluate and predict the business performance of logistics companies in Vietnam. The authors use the optimal algorithm in the data envelopment analysis (DEA) to evaluate the business efficiency of the companies in the years 2014–2017. In addition, the authors use Grey system theory to forecast business results and their future use during the period of 2018–2021. The research shows that Gemadept Corporation and Sea & Air Freight International use the their business resources effectively and as expected, and that these companies will continue to thrive in the future. This study provides a method to measure, evaluate, and forecast the business performance of the logistics companies. Managers and the government can rely on this approach for implementation and overall planning of logistics enterprises in the future.     

STABILIZATION WITH WAGE INDEXATION AND EXCHANGE RATE FLEXIBILITY

Abstract. This survey examines the role of wage indexation and exchange rate policy in dampening fluctuations in output around its target level. It is demonstrated that the appropriate choice for wage indexation and exchange rate flexibility is highly sensitive to the nature and the relative importance of the shocks impinging upon the economy, as well as to the relevant parameters in the economy. Moreover, the question of the desired flexibility of the exchange rate should be studied in the context of wage indexation, and vice versa. This interdependence raises the possibility of both policies being complements or substitutes to each other depending on the number of shocks that perturb the economy.     

Gathering Information and Exercising Influence: Two Forms of Civic Virtue Organizational Citizenship Behavior

Political behavior at work often is disparaged as self-serving activity that undermines the efficient pursuit of organizational goals. Yet politics has a more benign meaning as well: responsible participation in decision-making processes, keeping informed, and promoting innovative ideas that serve long-term organizational interests. To date, the negative image of organizational politics among managers and scholars has limited research on the positive contributions of responsible political participation, a form of Organizational Citizenship Behavior (OCB) known as civic virtue.This paper draws on political philosophy and organizational research to consider two forms of civic virtue OCB: gathering information and exercising influence. Both are proactive and can have beneficial results for individuals, organizations, and society. Conceptually, the two forms of civic virtue are related. Yet they also are different. Results of a field study of 245 employees and their supervisors provide support for similarities and differences in the two forms of civic virtue. We discuss theoretical and practical implications of our study, and the benefits of continued research on both aspects of civic virtue OCB.An earlier version of this paper was presented at the Society for Industrial and Organizational Psychology, Orlando FL, April 2003, in a symposium entitled “New Perspectives on the Dimensionality of Organizational Citizenship Behavior.” A newer version of this paper was presented at the October 2005 International Meeting of the Association on Employment Practices and Principles (AEPP) in Baltimore, MD.     

Application of Multilevel Models to Structured Repeated Measurements

The linear mixed-effects model has been widely used for the analysis of continuous longitudinal data. This paper demonstrates that the linear mixed model can be adapted and used for the analysis of structured repeated measurements. A computational advantage of the proposed methodology is that there is no extra burden on the analyst since any software for linear mixed-effects models can be used to fit the proposed models. Two data sets from clinical psychology are used as motivating examples and to illustrate the methods.     

Distribution-free test procedures in two-way layouts; a concept of rank-interaction

Summary  In this paper the concept of 'rank-interaction' is introduced and a distribution-free method for testing against the presence of 'rank-interaction' is suggested in the case of a two-way layout (classification) with m (> 1) observations per cell. Roughly speaking rank-interaction can be understood as the phenomenon at which the ranks of the levels of some relevant variable are different for different classes of the other factor. The exact null distribution of the test statistic has been computed in some cases. The asymptotic distribution under the null hypothesis has been derived. A test suggested by J.V. B radley in his book 'Distribution-free Statistical Tests' [2] is discussed. In the opinion of the authors it is doubtful whether the asymptotic distribution of the test statistic under the null hypothesis, as given by B radley , is correct. The test of B radley was intended to be sensitive to the presence of interactions defined in the usual way and hence not only to 'rank-interaction'. The same applies to methods proposed by some other authors. We claim that situations exist where one should test against rank-interaction and not against the usual more general alternative.
