The cyclical behavior of bank capital buffers in an emerging economy: Size does matter

Using a panel of Colombian banks and quarterly data between 1996:1 and 2010:3, we study the relationship between short-run adjustments in bank capital buffers and the business cycle. We follow a partial adjustment framework and control for several variables that have been identified as important determinants of bank capital buffers in previous studies, and find that bank capital buffers vary over the business cycle. We are able to identify a negative co-movement of capital buffers and the business cycle. However, we also find that capital buffers of small and large banks behave asymmetrically during the business cycle. While the former appear to be constant over time, once the appropriate set of control variables is used, the latter present a countercyclical behavior. Our results suggest the possible need of the implementation of regulatory policy measures in developing countries.     

Economic Reforms,Social Policy,and the Family Economy in Chile

Chile's long tradition of welfare programs included “generous” benefits for many working women. The social security system, however, perpetuated significant forms of gender and class inequality. In the 1970s and 1980s, poverty was greatly increased by sweeping market reforms. The military government responded to the high social costs with a minimal safety net which targeted expectant mothers, small children and the extremely poor, but was inadequate for most of the population. After the return of democracy, income distribution has improved in the 1990s. Yet, much needs to be done to promote family well-being through effective and participatory social policies.     

Facility location under demand uncertainty: Response to a large-scale bio-terror attack

In the event of a catastrophic bio-terror attack, major urban centers need to efficiently distribute large amounts of medicine to the population. In this paper, we consider a facility location problem to determine the points in a large city where medicine should be handed out to the population. We consider locating capacitated facilities in order to maximize coverage, taking into account a distance-dependent coverage function and demand uncertainty. We formulate a special case of the maximal covering location problem (MCLP) with a loss function, to account for the distance-sensitive demand, and chance-constraints to address the demand uncertainty. This model decides the locations to open, and the supplies and demand assigned to each location. We solve this problem with a locate-allocate heuristic. We illustrate the use of the model by solving a case study of locating facilities to address a large-scale emergency of a hypothetical anthrax attack in Los Angeles County.     

Efficiency,productivity and technology comparison for farms in Central and Western Europe: The case of field crop and dairy farming in Hungary and France

This paper investigates the differences in technical efficiency and productivity change, and the technology gaps, between French and Hungarian farms in the dairy and cereal, oilseed and protein crops (COP) sectors during the period 2001–2007. The analyses were performed with national Farm Accountancy Data Network (FADN) data and the Data Envelopment Analysis (DEA) approach under each country's respective frontier and under a metafrontier.Results reveal that French COP farms were on average more efficient under their own technology than Hungarian farms under theirs, but there was no difference between the two countries for dairy farms. However, metatechnology ratios calculated with the construction of the metafrontier indicate that Hungarian technology was the more productive in both the dairy and the COP sectors, but more noticeably in COP production.     

What Drives the Operating Performance of Privatised Firms?

Using a panel data analysis of Spanish privatised firms, we study how different factors influence the operating performance of divested companies. The results show that it is not privatisation per se but other factors that matter. After controlling for possible sample selection bias related to government timing of divestments, we find that the greater the relinquishment of State control and the smaller the percentage of ownership held by managers and/or employees, the better the firms’ post‐privatisation performance. Moreover, privatisations that are accompanied by liberalisation programmes and occur during buoyant economic cycles turn out to be more successful.     

Impacts of 2003 CAP reform on land rental prices and capitalization

Based on a graphical analysis, we investigate the impacts of the Fischler Reform of the Common Agricultural Policy on land rental prices and the capitalization of single farm payments (SFP) into land values. The model shows that the degree of capitalization mainly depends on the scarcity/surplus of SFP entitlements relative to eligible hectares, the implementation model (historical versus regional) and the land supply elasticity. If there are more SFP entitlements than eligible hectares, the degree of capitalization into land values may not decline and may even increase due to the inclusion of other supports such as animal premiums in the SFP. We test this hypothesis with an empirical analysis of cross-section data on land rental prices in Bavaria for 2005. Empirical results indicate that decoupled SFP are capitalized into rental prices to a larger degree than the coupled direct payments of the time prior to the reform.     

Multi-unit auctions with private information: an indivisible unit continuous price model

We construct a model of multi-unit auctions in which I bidders bid for two indivisible units of a common value good. Using a first-order approach, we find that there are equilibria in which bidders bid the same price for both units in the discriminatory auction, but not in the uniform auction. When there are only two bidders, under certain conditions, there are linear equilibria for both the discriminatory and the uniform auction formats. In all equilibria, bidders equalize the expected marginal benefit of bidding to the marginal costs of bidding. We show that comparison of the seller??s expected revenue across auction formats depends only on the ratio of the precision of private information to the precision of public information.     

Value creation through production offshore–inshore strategies in a footwear industry cluster: A coevolutionary perspective

In many industries, production offshoring towards countries with low labour costs has been a common trend in recent decades. However, we find some resistance to dismantling factories in a footwear industry cluster in Spain. From a customer perspective of value creation, and based on qualitative and quantitative data, we analyse the evolution of firms’ offshore–inshore strategies associated with the main periods of cluster expansion and contraction over the last 25 years. We highlight three main findings. First, the pressures of the environment can terminate firms but not necessarily the entrepreneurial orientation of their owners to continue in the same industry. Second, adaptive processes to create value for the consumer in the footwear industry seek a balance between production offshoring and domestic production in order to optimize the firm's competitive position. Third, coevolutionary theory should consider not only the selection and adaptation processes but also the capacity of firms to influence their environment, since the alternative strategies to create value for customers in footwear industry have resulted in speeding up the footwear fashion market. We also suggest implications for research and practice.     

Corporate governance and impression management in annual results press releases

We study the association between corporate governance and impression management in annual results press releases (ARPRs). Press releases constitute a timely vehicle to communicate firm performance to third parties but they can be manipulated to distort readers’ perceptions of corporate achievements. We predict that governance mechanisms actively monitor managerial disclosures, improving firm transparency and thus reducing impression management in ARPRs. The results confirm that strong governance limits impression management, consistent with governance monitoring effectively reducing self-serving disclosures by management. Our evidence suggests that management disclosure practices respond, at least partly, to informative motivations. We also show that strong governance firms are more likely to release an ARPR.     

Epstein–Zin Utility in DICE: Is Risk Aversion Irrelevant to Climate Policy?

Climate change involves uncertain probabilities of catastrophic risks, and very longterm consequences of current actions. Climate economics, therefore, is centrally concerned with the treatment of risk and time. Yet conventional assumptions about utility and optimal economic growth create a perverse connection between risk aversion and time preference, such that more aversion to current risks implies less concern for future outcomes, and vice versa. The same conflation of risk aversion and time preference leads to the equity premium puzzle in finance. A promising response to the equity premium puzzle, the recursive utility of Epstein and Zin, allows separation of risk aversion and time preference—at the cost of considerable analytic complexity. We introduce an accessible implementation of Epstein–Zin utility into the DICE model of climate economics, creating a hybrid “EZ-DICE” model. Using Epstein–Zin parameters from the finance literature and climate uncertainty parameters from the science literature, we find that the optimal climate policy in EZ-DICE calls for rapid abatement of carbon emissions; it is similar to standard DICE results with the discount rate set to equal the risk-free rate of return. EZ-DICE solutions are sensitive to the intertemporal elasticity of substitution, but remarkably insensitive to risk aversion. Insensitivity to risk aversion may reflect the difficulty of modeling catastrophic risks within DICE. Implicit in DICE are strong assumptions about the cost of climate stabilization and the certainty and speed of success; under these assumptions, risk aversion would in fact be unimportant. A more realistic analysis will require a subtler treatment of catastrophic climate risk.
