Illiquidity Premium in the MILA

This article analyzes the illiquidity premium in the MILA. Using seven proxies for illiquidity, we find a positive and significant illiquidity premium for our sample. A microstructure bias-free portfolio weighting based on past returns is critical in our finding of an illiquidity premium, which is robust to several methodological changes in our portfolio simulations. We also document that the premium is present only in small and high book-to-market stocks. Nonetheless, when we control for size and distress effects, the difference and significance in risk-adjusted returns between portfolios of high and low illiquidity stocks remains.     

Adaptive market efficiency of agricultural commodity futures contracts

In this paper we investigate the adaptive market efficiency of the agricultural commodity futures market, using a sample of eight futures contracts. Using a battery of nonlinear tests, we uncover the nonlinear serial dependence in the returns series. We run the Hinich portmanteau bicorrelation test to uncover the moments in which the nonlinear serial dependence, and therefore adaptive market efficiency, occurs for our sample.     

Disciplina de mercado en el sistema bancario centroamericano

This article empirically tests the market discipline hypothesis in the Central American banking system. Whether the riskier banks (with the worst bank fundamentals) pay higher interest rates and attract fewer amounts of deposits. We use dynamic panel data models and the generalized method of moments (SYS GMM) estimator, and a sample of 30 banks from six Central American countries over the years 2008-2012. In contrast to most of the previous empirical literature, particularly in developed countries, in Central America we did not find evidence for market discipline. The results are robust to different indicators of the bank fundamentals, to the effect of the internal demand for funding by banks, and to other econometric methods. These findings indicate weakness in the disclosure policy of banking information.     

Trading with Neighbors: Regional Stock Exchange Integration—The Mercado Integrado Latinoamericano

ABSTRACT

Who gains from the regional integration of stock exchanges? Exploring this question can identify motivators driving stock exchange integration between countries, and contribute to the wider debate whether such perceived gains are likely. This article examines the Latin American Integrated Market (MILA), currently comprised of Chile, Colombia, Mexico, and Peru. The plan, process, and difficulties facing MILA are examined. We conclude that investors from the region appear poised to reap the greatest rewards in the long-term, while regional brokers and investors, especially those based in Peru, have benefited most from the operation of MILA since 2011.     

Stock recommendations and investment portfolio formation: A study in the Brazilian market

The stock analysts have a relevant role in the capital market, since, directly or indirectly, they contribute to the paper pricing and to the composition of the investment portfolio. The purpose of this study is to verify if it is possible to obtain extraordinary returns, above those offered by a market portfolio, with the monitoring of the stock recommendations issued by Brazilian capital market analysts, one of the most important in Latin America. Based on a wide range of consensual recommendations concerning the period from 2000 to 2010, and with the monitoring of the historical series of paper returns covered by the analyses, the performance of two portfolios were compared, one formed by stocks that received favorable and the other one formed by stocks that received unfavorable analyst recommendations. The results showed bias in recommendations, since there is, systematically, a greater number of favorable against unfavorable recommendations. The results mainly showed that the analysts were unable to identify the stocks that actually offered greater returns within the period considered.     

Market discipline in the Central American banking system

The hypothesis of market discipline is empirically verified in the Central American banking system. A contrast is carried out on whether the riskier banks (the ones with the worst banking fundamentals) pay higher interest rates and receive smaller amounts in deposits. The generalized method of moments is used for dynamic panel data models (the SYS GMM estimator), as well as a sample of 30 banks from six Central American countries during the 2008–2012 period. Unlike the majority of the previous empirical literature, specifically for developed countries, no evidence of market discipline was found in Central America. The results are robust for several indicators of the banking fundamentals for purposes of internal demand of bank capital, and for other econometric models. These findings indicate weaknesses in the bank policy regarding the disclosure of information.     

Formation of monopolies in a bipartite market

We study the formation of monopolies in a simplified economic model where two brands compete in the market, using an agent based model. Each agent represents a company that uses one of the two available brands and interacts with other companies. The brands continually improve their product in order to compete for market share. In the innovation process companies can decide to change to the other brand if the move is beneficial. There is a cost for the company if it decides to switch to the other brand, and another cost if it stays with its current brand but only upgrades to a new enhanced version of the product. Our simulations show that the system always reaches a state when all companies end using a single brand, which is equivalent to a monopoly. We study the time span needed to reach the single brand final state for different parameters of the model.     

Analysis of the hysteresis of unemployment in Mexico in the face of macroeconomic shocks

This research presents the behavior of the Mexican unemployment rate and shows the dependence with own history and macro variables. The concept of hysteresis or persistence tries to separate this inertia in the unemployment rate and some macroeconomic and endogenous factors. The results show a high inertia in the Mexican labor market, justified by the monetary levels and the dependence of the investment levels, considering the shocks of exports that affect the unemployment in the long term.
