Announced layoffs: Their effect on corporate financial performance

Conventional wisdom holds that when a firm gets into trouble due to lagging sales and rising costs, cutting the size of the organization to reduce fat and waste is a normal and effective response. In this study, evidence was found to suggest that just the opposite might be true. The financial performance of Fortune 100 companies was tracked over a five-year period—two years prior to the announced layoff, the year of the layoff announcement, and two years following it. Contrary to expectations, the results indicate that financial performance worsened, rather than improved, following announced layoffs. Strategic and human resource implications for the management of corporate downsizing are provided.     

Risk and Capital Structure in the Regulated Firm

This paper studies the role of capital structure in a regulated firm. We show that it affects the prices set by the regulator, the expected price being lower the higher the proportion of debt finance. However, when debt is increased beyond a certain level, the benefit of lower expected prices is offset by their increased variability. We also study the socially preferred capital structure. This is such that consumers carry some risk, in the form of higher prices in adverse economic conditions.     

Specialisation,localisation, and trade value in the wake of cross-border production sharing. The Central Eastern European Countries' case

We focus on five among the sectors in which most of the CEECs’ trade in middle products with EU-15 is concentrated. Over the second half of the 1990s, we observe remarkable changes in both production and trade specialization as well as a significant relocation of industries within CEECs. Using jointly trade and production data we outline co-movements in the adjustment of specialisation patterns. We also show that the redistribution of activities at the regional level reflects the relocation of industries at the global level. Finally, we try to detect the scope of fragmentation of production characterizing each industry and the ways in which CEECs are moving along the “internationally sliced-up value chain”.

The politics of redistributive social insurance

This paper analyses the political support for a social insurance that includes elements of redistribution when there exists an imperfect private insurance alternative. Individuals differ both in their income and risk. The social insurance is compulsory and charges an income-related contribution with pooling of risks. The private insurance is voluntary and charges a contribution based on individual risks. However due to the adverse selection problem, private insurance companies provide only partial insurance. Adopting a non-expected utility model, we show that there is a general majority support for social insurance and that this support is increasing with risk aversion. We also show that a mixed insurance is politically impossible, regardless of the degree of redistribution of social insurance and the joint distribution of risk and income in the population. Lastly, we analyse how the political support for social insurance is affected by any change in its redistributive component and the possibility of using genetic tests.     

GAME THEORETIC MODELS OF MIXED OLIGOPOLY

Abstract. In this paper we review various models that have been proposed for the study of mixed oligopoly, that is markets in which private and public firm compete on equal basis using only market instruments.     

On the Evaluation of Economic Mobility

This paper presents a framework for the evaluation and measurement of "reversal" and "origin independence" as separate aspects of economic mobility. We show that evaluation depends on aversion to multi-period inequality, aversion to inter-temporal fluctuations, and aversion to future risk. We construct "extended Atkinson indices" that allow us to quantify the relative impact of reversal and origin independence on welfare. We apply our approach to the comparison of income mobility in Germany and in the U.S.. When aversion to inequality is the only consideration, the U.S. gains more from mobility than Germany. This reflects similar gains from reversal in the two countries but greater gains in the U.S. from origin independence. The introduction of aversion to intertemporal fluctuations and aversion to future risk makes the impact of mobility in the two countries more similar.     

Embodied technological change in supplier dominated firms

This paper identifies the role of new capital goods as the main external source of innovation for supplier dominated firms belonging to traditional consumer good industries. After a brief survey on the role of inter-industry technology flows, the results of a field study are presented concerning the amount of technological change embodied in the new machinery acquired during the 1980s by a sample of Italian manufacturing firms producing traditional consumer goods. We show that industries and firms differ in the quality of technological change embodied in (or allowed by) new capital goods, and that such differences depend on industry-specific and firm-specific factors. The former primarily refer to product characteristics, the latter mainly to the age and the affiliation of the firm with an industrial group. The final section contains some policy suggestions for fostering the diffusion of new machinery (embodying technological change) among small firms and traditional industries.     

Public pricing of final and intermediate goods in the presence of externalities

The purpose of this paper is to investigate the impact of externalities on pricing decisions by a public or a private regulated firm selling both final and intermediate goods. The externalities generate feedbacks in demand that affect both consumers and producers. The model is very general in that it does not impose constant returns to scale on private production, allows for distributional effects of both the publicly determined prices and private sector profits, and captures the general equilibrium effects of public pricing. Socially optimal pricing rules are derived, and the relation of the results with previous models of pricing in the presence of externalities is investigated.     

Investigating the solvency of brazilian credit unions using a proportional hazard model

Abstract ** : Due to high interest rates and bank spreads, the number of credit unions in Brazil has increased over recent years. As financial institutions, these cooperatives need tools to signal impending financial problems. This paper focuses on one tool that can be used to evaluate credit union solvency: the Cox Proportional Hazards Model. A sample of 80 credit unions from the Brazilian state of Minas Gerais was selected to supply data. The analysis period is between December 2001 and June 2003. The results indicate that the relevant indicators for insolvency prediction are, in descending order of predictive ability, General Liquidity, Salary and Benefit Expenses, and the Loan/Equity Ratio. In general, results produced using the delineated theoretical model were in consonance with international literature .
