A computational approach to resource allocation in spatial urban models

This paper synthesizes and generalizes recent literature on the use of ‘fixed point methods’ to compute approximate numerical solutions to general equilibrium models of urban land use. We show how a broad array of spatial urban models, including ones involving endogenously generated externalities, can be studied within the context of a single unifying computational framework.     

Growth, inequality, and welfare: comparisons across space and time

We propose and apply several welfare measures that combine averageincome with a measure of inequality to undertake cross-countrycomparisons of aggregate welfare for the 1970 to 2000 period.Our welfare measures, which are based on theoretical and empiricalfindings on the role of inequality in social welfare, drasticallychange the impression of levels of welfare, significantly affectthe welfare ranking of countries in different benchmark years,affect changes in ranking over time, and affect convergencebetween industrialized and developing countries. While the resultsare sensitive to the type of inequality and its presumed effecton welfare, the results are robust to different ways to addresscomparability problems inherent in the inequality data used.     

Reorganizing Czech Businesses: A Bankruptcy Law Reform under a Recession Stress‐Test

The new Czech Insolvency Act, featuring a brand new reorganization option for business debtors, has now been in force for over 3 years—a period of a severe downturn in the Czech (and the global) economy. This presents an opportunity to observe the workings of the new insolvency law on a “recession‐loaded” empirical dataset extracted from the on‐line insolvency register also introduced as part of the reform. This is the goal of this article, the subject matter of which is an initial empirical look at insolvency proceedings conducted over debtors whose reorganization attempts had been allowed in the years 2008 and 2009.

Don't They Care? Or,Are They Just Unaware? Risk Perception and the Demand for Long‐Term Care Insurance

The potential need for long‐term care (LTC) is one of the greatest financial risks faced not only by the elderly but also by their adult children, who often provide care or financial assistance. We investigate adult children's role in the demand for LTC insurance. Similar to flood insurance, we find that demand for LTC insurance is low due to low risk perception. The more aware adult children are of the risk, the more likely LTC insurance is to be purchased, either by the children themselves on behalf of their parents or by the parents under the influence of their children.     

Financial participation and recruitment and retention: causes and consequences

Using a sample of over 5000 establishments in Germany, we analyze the antecedents and effects of profit sharing (PS) and employee share ownership (ESO) with respect to the ability of firms to meet their recruitment and retention objectives and to achieve employment growth. We draw on both economic and behavioral perspectives to argue that firms that adopt PS and ESO plans do so in order to attract and retain employees. Using logistic regression and a propensity score matching technique, we find that firms that face higher recruitment problems, and those that have greater employment growth objectives, are more likely to use ESO and PS. Unlike ESO, PS enhances firm-level employment growth. However, neither ESO nor PS help firms to fully resolve recruitment and retention problems.     

Estimating an equilibrium exchange rate for the dollar and other key currencies

In this paper, we adapt the concept of fundamental equilibrium exchange rates ‘FEER’ in a complete model approach. We use it to determine the likely paths of the Dollar and other key currencies. The FEER is the (real) exchange rate that is consistent with internal balance and sustainable external balances. Here we examine the composition of a Dollar adjustment and hence the extent to which a FEER (for the US) depends on factors or rigidities elsewhere in the world, as well as at home. We find, the US still needs to accept an adjustment in her real exchange rate if the increase in her foreign liabilities is to come to an end. However, counterpart adjustments also have to be made in Canada, Mexico, and some Asian economies if this policy is to be successful. We also show that productivity growth differentials may act as a substitute for depreciation, and this provides an explanation for the failure of the dollar to depreciate in the 1990s.     

Infinite inequality systems and cardinal revelations

Summary. Many economics problems are maximization or minimization problems, and can be formalized as problems of solving linear difference systems of the form and r _k -r _l > c _kl , for r-unknowns, with given c-constants. They typically involve strict as well as weak inequalities, with infinitely many inequalities and unknowns. Since strict inequalities are not preserved under passage to the limit, infinite systems with strict inequalities are notoriously hard to solve. We introduce a unifying tool for solving them. Our main result (Theorem 1 for the countable case, Theorem [2] for the not-necessarily-countable case) introduces a uniform solvability criterion (the -Axiom), and our proof yields a method for solving those that are solvable. The axioms economic intuition extends the traditional ordinal notion of revealed preference to a cardinal notion. We give applications in producer theory, consumer theory, implementation theory, and constrained maximization theory.Received: 21 May 2003, Revised: 29 October 2004, JEL Classification Numbers: C69, D21, D11, D82.

Optimal Management Under Institutional Constraints: Determining a Total Allowable Catch for Different Fleet Segments in the Northeast Arctic Cod Fishery

Many real world fisheries have an individual vessel quota system with restrictions on transferability of quota or entrance of new vessels into the fishery. While the standard economic reasoning is that these institutional constraints lead to welfare losses, the size of those losses and optimal second-best policies are usually unknown. We develop a dynamic bioeconomic model, in which a scientific body provides an optimal TAC given restrictions on (i) transferability between vessel segments and (ii) entrance of new vessels. Further, we also quantify welfare losses arising from not maximizing economic welfare, but physical yield—which is actually the case in many fisheries. We apply the model to the Northeast Arctic cod fishery, and estimate not only the cost and harvesting functions of the various vessel types, but also the parameters of the biological model as well as those of the demand function. This allows us to determine optimal second-best policies and quantify corresponding welfare effects for our case study fishery.
