Sharing Rules in Teams

We examine the problem of output sharing in a moral hazard in team situation. Although we do not consider any particular procedure, we assume that the team uses some procedure to decide a sharing rule before actual production takes place (for example, this may be a bargaining process or a team welfare maximization problem). This must take into account that the team will play a noncooperative game in the production process conditional on the chosen sharing rule. We show that the procedure for deciding the sharing rule does not have to look for anything more complicated than simple linear sharing rules. We also show that, when there is limited liability, the procedure needs to consider only the slightly more complicated piecewise linear rules. As a consequence of the linear sharing rule result, we are also able to provide a characterization of implementable outcomes.

What's in a name? Anonymity and social distance in dictator and ultimatum games

The standard procedure in experimental economics maintains anonymity among laboratory participants, yet many field interactions are conducted with neither complete anonymity nor complete familiarity. When we are involved in interactive situations in the field, we usually have some clues concerning the characteristics of others; however, in some environments (such as e-commerce) these clues may not be very substantial. How will people respond to varying degrees of anonymity and social distance? We consider the effect of one form of social distance on behavior by comparing the standard procedure of playing dictator and ultimatum games with the same games played by participants who knew the family name of their counterparts. When these names were revealed, dictators allocated a significantly larger portion of the pie. However, this information had no significant effect on the offers in the ultimatum game, as it appears that strategic considerations crowd out impulses toward generosity or charity.     

Estimating Costs of Children from Micro-Unit Records: A New Procedure Applied to Australian Data

Measuring the costs of children is of immense practical importance in a range of economic and social policy areas. In this paper, we introduce a new econometric procedure that improves on existing methods for obtaining estimates of such costs from a demand system. We develop, using an extended linear expenditure system, an iterative maximum likelihood estimator that overcomes possible estimation problems that arise from the 2-step estimation procedures employed by earlier authors. We also allow for a more general assumption about the equation “errors”, that of non-zero correlation between the errors for different commodities in the same household. Another important contribution is the development of an estimation procedure for sets of seemingly unrelated regressions where the different sets of equations are linked by some common parameters. The proposed procedure is applied to the 1988–89 and 1993–94 Australian Household Expenditure Surveys and results obtained update estimates of both the commodity-specific and general scales previously obtained for Australia.

     

Elementary results on solutions to the bellman equation of dynamic programming: existence,uniqueness, and convergence

We establish some elementary results on solutions to the Bellman equation without introducing any topological assumption. Under a small number of conditions, we show that the Bellman equation has a unique solution in a certain set, that this solution is the value function, and that the value function can be computed by value iteration with an appropriate initial condition. In addition, we show that the value function can be computed by the same procedure under alternative conditions. We apply our results to two optimal growth models: one with a discontinuous production function and the other with “roughly increasing” returns.     

Does antidumping use contribute to trade liberalization in developing countries?

Abstract .  Some supporters of antidumping have argued that this procedure serves as a kind of 'safety valve' for protectionist pressure. In this paper, we investigate whether there is empirical evidence that the use of antidumping actions has contributed to ongoing tariff reductions over the period 1988 to 2004 in a sample of 23 developing countries, some of which have become aggressive users of antidumping in recent years. The evidence is not supportive of the safety valve argument for these countries. Instead, evidence suggests that past use of antidumping may have led to less rather than more trade liberalization.     

An empirical estimation for mean-reverting coal prices with long memory

In this paper we discuss the calibration issues of power models built on mean-reverting processes combined with long memory. The unknown parameters of fractional mean-reversion processes are estimated by a hybrid estimation method, which is built upon the marriage of the quadratic variation and the least squares. We perform a simulation study to test the efficiency of these estimators and to compare with the approach proposed by Høg (1999). Moreover, we apply our estimation procedure to some sample series of Chinese coal spot prices in real life situations. These results support the use of fractional mean-reversion processes in modeling Chinese coal prices.     

Optimal guessing: Choice in complex environments

In this paper, we extend the analysis of our earlier work on boundedly rational learning in an i.i.d. setting [Easley and Rustichini, Econometrica 67 (1999) 1157-1184] to complex decision problems. We show that the axioms from our earlier analysis can be applied in this more complex setting, and along with some new axioms, they asymptotically yield expected utility maximization. Perhaps most important is our demonstration of a simple procedure that insures expected payoff maximization no matter what Markov process the underlying process on states follows. We view this result as providing a positive learning result for all worlds in which learning is possible.     

Nonparametric Regression and Causality Testing:A Monte-Carlo Study

In this paper we propose a new procedure for causality testing using nonparametric additive models. We argue that the major advantage of our proposed method is that it can be used if the underlying data generation process (DGP) is either linear or nonlinear. Our results show that the nonparametric testing procedure provides a more robust test of causality. Furthermore, we show that the loss of power associated with the nonparametric procedure is minimal if the true DGP is linear.     

Stable lexicographic rules for shortest path games

For the class of shortest path games, we propose a family of new cost sharing rules satisfying core selection. These rules allocate shares according to some lexicographic preference relation. A computational procedure is provided. Our results relate to those of Tijs et al. (2011).     

A warning on the use of the Cochrane-Orcutt procedure based on a money demand equation

Betancourt/Kelejian [1981] have recently warned against using the Cochrane-Orcutt procedure in models which include a lagged endogenous variable because this procedure can have more than onefixed point even asymptotically. FollowingSargan [1964], we argue instead that fixed points are not necessarily minima and that the question of practical importance is whether the residual sum of squares can have multipleminima. Within this formulation of the problem, we provide the firstreal example of multiple minima obtainable by the Cochrane-Orcutt procedure — with or without a lagged endogenous variable — and use it to caution against routine use of this procedure.     

On the application of the rank tests for nonlinear cointegration to PPP: The case of Papua New Guinea

Much interest has been paid recently to the nonlinear cointegrating relations existing among economic variables. Various testing procedures are already available to test for the existence of nonlinear cointegration. For example, Breitung (2001) proposes rank tests and his testing procedure has been broadly applied. In this study, we warn against a blind application of the rank cointegration tests, particularly to economic variables that evidence certain behavior. As an illustration, we employ the nominal exchange rates and relative prices of Papua New Guinea against her major trading partners with the objective of testing the validity of purchasing power parity for the country. Our simulation results also confirm our warnings. Additionally, we provide some simple solutions to the problem we encounter herein.     

A Monte Carlo test of preference independence

Theil (1987) recently developed distribution-free Monte Carlo testing procedures for demand homogeneity and Slutsky symmetry which do not use asymptotic theory. In this paper we introduce a similar procedure to test preference independence. The application of this procedure is illustrated with Dutch data.     

Private saving in India and Malaysia compared: the roles of financial liberalization and expected pension benefits

In this article, we provide a comparative account of the evolution of private saving in India and Malaysia, and analyze how policy changes in the financial sector and pension system help explain differences in their saving performance. Using the Autoregressive Distributed Lag (ARDL) bounds estimation procedure, we find a fairly robust long-run relationship between private saving and its determinants in both countries. Consistent with the predictions made in the life cycle model, our results indicate that higher income growth stimulates private saving and an increase in age dependency retards private saving. The results provide some support for the hypothesis that financial liberalization results in lower private saving in both countries. The evidence also indicates that expected pension benefits tend to stimulate private saving in India, but that the reverse is found in Malaysia.     

The causality direction in consumption–income process and sensitivity to lag structures

Using the statistical procedures developed by Granger (1969) and Sims (1972), the causality direction in the consumption–income process is examined in this study. The results provide some justification in concluding that the causality direction is from income to consumption. It can also be seen that the results of causality tests are very sensitive to the lag lengths employed. The statistical procedure, which is based on Grangers's contribution, appears to be more consistent than Sims's procedure.     

THE IMPORTANCE OF REPUTATION IN AWARDING PUBLIC CONTRACTS

ABSTRACT * :  The main economic literature emphasizes that the efficiency of the awarding procedure depends on the contractual rules, especially those regarding firm's remuneration. In this work we show the existence of a reverse link: when the enforcement of contractual terms is imperfect, the rules of the awarding mechanism can help to improve the efficiency of the contractual relationship. In some circumstances, awarding rules based only on bids are not able to deal with the problem of opportunistic behaviour during the execution of the contract. Our model points out that the public administration can incentivize the contractor's fairness by considering not only competitors' bids, but also their different reputation.     

Stationary equilibria in stochastic games: structure, selection, and computation

This paper introduces an algorithm to compute stationary equilibria in stochastic games that is guaranteed to converge for almost all such games. Since in general the number of stationary equilibria is overwhelming, we pay attention to the issue of equilibrium selection. We do this by extending the linear tracing procedure to the class of stochastic games, called the stochastic tracing procedure. As a by-product of our results, we extend a recent result on the generic finiteness of stationary equilibria in stochastic games to oddness of equilibria.     

The estimation of a hedonic asking and offer rent equation model: An EM algorithm approach

In this paper we claim that modeling housing markets, specifically the rental housing market, should be based on some sort of disequilibrium framework. We posit a model of asking and offer rents in the spirit of a sample selectivity model. This approach allows us not only to test whether landlords and tenants agree upon the marginal evaluations of unit attributes, but also to estimate the impact on rental demand of tenant specific attributes such as family income and race. Since estimators obtained from this procedure are consistent, but not efficient in this two equation context, we employ an EM algorithm in our estimation in order to obtain MLE equivalent estimators. We have found that our data support the use of this disequilibrium approach in that the coefficient estimates for the asking rent equation, under the assumptions of a sample selectivity model, are not coincident with those obtained from an uncorrected equation.     

Use of the principal component method in the maximum likelihood estimation procedure of the logit model

The maximum likelihood estimates of a qualitative response market are solved by an iterative procedure. When severe multicollinearity exists among the explanatory variables, this procedure may fail to converge. In this note, using a bank-failure model, we demonstrate how the principle component method can make the iterative procedure converge when it fails to do so in the untransformed model.     

How effective is the Free Trade Agreement in South Asia? An empirical investigation

We investigate the efficacy of preferential trade liberalization in changing the observed trade pattern among the South Asian countries that have entered into the South Asian Free Trade Agreement (SAFTA). Although in its nascent stage, some data are now available to provide an ex-post evaluation of the performance of this bloc. Using these data, we find no empirical evidence of trade creation among SAFTA members, which is not surprising given that tariff concessions in SAFTA are small and are offset by complicated rules of origin procedure. However, a substantial and statistically significant increase in exports from SAFTA members to the rest of the world is found. Several panel strategies are used to check the sensitivity of the results against the assumptions of the estimation strategies. As some key coefficient estimates are found to differ across estimation methods, policymakers in South Asia need to use care in relying on the results from empirical studies, including our own, in formulating their trade policies.
