OPTIMAL REINSURANCE AND DIVIDEND DISTRIBUTION POLICIES IN THE CRAMÉR-LUNDBERG MODEL

We consider that the reserve of an insurance company follows a Cramér-Lundberg process. The management has the possibility of controlling the risk by means of reinsurance. Our aim is to find a dynamic choice of both the reinsurance policy and the dividend distribution strategy that maximizes the cumulative expected discounted dividend payouts. We study the usual cases of excess-of-loss and proportional reinsurance as well as the family of all possible reinsurance contracts. We characterize the optimal value function as the smallest viscosity solution of the associated Hamilton-Jacobi-Bellman equation and we prove that there exists an optimal band strategy. We also describe the optimal value function for small initial reserves.     

Remittances and Development in Latin America

Flows of workers’ remittances have become a major source of external finance for developing countries and are particularly important in Latin America and the Caribbean, where they are estimated to have reached $40 billion in 2004. Not surprisingly, academics, policymakers and development practitioners in general have been devoting increasing attention to the potential development impact that these flows may have on receiving countries. This paper contributes to this debate along four dimensions. First, it reviews the evolution of remittances flows to Latin America, using Balance of Payments data, and compares these statistics with estimates of remittances income based on Household Surveys. Second, the paper describes the varying profile of remittances recipients in ten Latin American countries. Third, the paper reviews the few macro‐ and microeconomic studies that have estimated the impact of remittances on poverty and inequality. Finally, the paper expands some of the existing works to investigate the extent to which that impact is different in Latin America and varies across countries in the region.     

Biofortification,biodiversity and diet: A search for complementary applications against poverty and malnutrition

Biofortification, the focus of the HarvestPlus program of the Consultative Group on International Agriculture Research (CGIAR), represents a potentially powerful tool to increase dietary intake of essential nutrients in staple foods. This paper evaluates the compatibility of biofortification with the preferred option of dietary diversification and its potential impacts on the agricultural biodiversity essential for long term sustainability. In poor countries, biofortification requires increasing public investment in agricultural research and infrastructure for success. Rather than cereal commodities, biofortification for developing countries should focus on vegetatively propagated species or in improving quality of coarse cereals, as well as fodders. Community participatory approaches that identify local food resources with nutritional, agronomic and economic advantages to small-scale farmers could complement and set targets for biofortification as one of many approaches to alleviate nutritional deficiencies. Furthermore using agricultural biodiversity to reinforce dietary diversity can help situate biofortification within the larger context of sustainable food-based approaches. In this light, this paper evaluates specific biofortification interventions from environmental, sociocultural, political, economic, ethical, and biomedical perspectives.     

The Real Options Component of Firm Market Value: The Case of the Technological Corporation

Abstract:   This paper tests whether stock prices reflect investor's expectations regarding the value of real options. The analysis is implemented based on a sample of 391 high‐tech companies listed on main OECD stock markets during the period December 1994 through December 2000. Results confirm the predicted relation between the fraction of a firm's market value not accounted for by its assets‐in‐place, and a series of variables that are assumed to disclose its real options value, variables such as research and development activity, risk and skewness of stock returns, and size. The results are robust even after controlling for valuation date, sub‐industry, country, and alternative measures of risk.     

Inside–outside money competition

We study how competition from privately supplied currency substitutes affects monetary equilibria. Whenever currency is inefficiently provided, inside money competition plays a disciplinary role by providing an upper bound on equilibrium inflation rates. Furthermore, if “inside monies” can be produced at a sufficiently low cost, outside money is driven out of circulation. Whenever a ‘benevolent’ government can commit to its fiscal policy, sequential monetary policy is efficient and inside money competition plays no role.     

An analysis of differentiation strategies for Galician thermal centres

In the modern tourism industry, competitiveness no longer can be based solely on price; rather, it is necessary to consider other aspects that might generate competitive advantages. In particular, the provision of a wide range of products, services and activities, all of outstanding quality, may be decisive for creating greater demand. Thermal establishments are well aware of these dynamics. Accordingly, this research analyses, using quantitative techniques, whether Galician thermal establishments, including health resorts, spas and thalassotherapy centres, have achieved well-defined differentiation strategies.     

How do transport costs affect firms’ exports? Evidence from a vanishing bridge

In this paper we provide estimates of the effects of international transport costs on firms’ exports and disentangle the channels of these effects. In so doing, we use a unique dataset consisting of highly disaggregated transaction-level trade and transport cost data and, in order to account for endogeneity, we exploit the exogenous variation in these costs associated with the non-trade related closure of the main bridge connecting two countries.     

MATCHING MARKETS WITH MIXED OWNERSHIP: THE CASE FOR A REAL‐LIFE ASSIGNMENT MECHANISM*

We consider a common indivisible good allocation problem whose popular applications include on‐campus housing, kidney exchange, and school choice. We show that the so‐called New House 4 (NH4) mechanism, which has been in use at MIT since the 1980s, is equivalent to a natural adaptation of the well‐known Gale–Shapley (GS) mechanism. We run two experiments comparing NH4 with the prominently advocated Top Trading Cycles (TTC) mechanism and NH4 with GS. We find that under NH4, the participation rate is significantly higher than under TTC. Based on a new ordinal test of efficiency, NH4 is more likely to Pareto dominate TTC.     

Trade associations and collusion among many agents: evidence from physicians

We study a recent case where most gynecologists in one city formed a trade association to bargain for better rates with insurance companies. After unsuccessful negotiations, the physicians jointly terminated their insurer contracts and set a minimum price. We find that subsequent realized prices coincided with Nash-Bertrand prices, and that the minimum price was barely binding. We show that these actions ensured the association's stability and increased profits. Our findings shed light on the role of trade association in collusion among a large number of heterogeneous agents, and provide insights for the antitrust analysis of trade associations.     

European banks’ executive remuneration under the new European Union regulation

We review how the new European regulation of bank executive compensation could affect the future of banking in Europe. Although there is no conclusive empirical evidence on the relation between bank executive remuneration and the financial crisis, authorities have intensively regulated the compensation of bank managers to eliminate risk-taking incentives in the financial industry. However, the new regulation could have unintended consequences of creating an adverse selection problem at European banks, reducing the number of best-performing managers available for European banks, and motivating an excessive increase in fixed remuneration over total remuneration, altering the way incentive systems work.
