The recent economic interaction between Latin America and Asia, particularly between Brazil and China, has attracted the attention of the academic world that seeks to understand the effects of this approach in terms of business cycle convergence, economic structure and development trajectory. This paper contributes to this debate, presenting new evidence about the type and quality of this relationship. Our results reveal that Brazil and China present different patterns of relationship between trade and productive specialization: while Brazil has an intra-industry trade pattern, China has an inter-industry trade pattern. We explore some normative implications and future research possibilities.  相似文献

Abstract ** : This paper estimates a human capital model for co‐operative managers and compares the results with the social capital model, based on a questionnaire distributed in Portugal in 2003. The study disentangles the relative contributions of the two competing theories of earnings: the human capital and social capital theories, as applied to co‐operative managers. We conclude that co‐operative managers' earnings are a function of both theories. Policy implications are derived .  相似文献

This article provides a means for testing whether buyers or sellers are responsible for a drop in sales following a market shock. We show that suppliers’ responses dominated the market reaction to the 2006 US Food and Drug Administration warning to avoid fresh spinach contaminated with potentially deadly bacteria Escherichia coli O157:H7. A modified Durbin-Wu-Hausman test for temporary price endogeneity is developed and used in a leafy green vegetable demand model. Test results indicate the price of bagged spinach was exogenous before the announcement but endogenous for approximately 12 weeks afterward. We show these results are consistent with the notion that suppliers temporarily limited the availability of spinach to consumers. Instead of consumers choosing the quantity purchased given exogenous prices, it was suppliers who limited the quantity marketed and consumers’ choices established the market price.  相似文献

We investigate the low prices preferences and the optimal relative tick size hypotheses, as possible explanations of the stock split execution effects in a pure order-driven and multi-tick market. Using intraday data for the Spanish Stock Exchange during 1997-2001, we find that stock splits do not improve liquidity but do change trading composition. Following splits, small trades from retail investors increase significantly, especially in the larger stock splits. However, we find that this effect seems to disappear with the new tick-size rules adopted by Spanish market in 1999. We extend the optimal relative tick size hypothesis for a multi-tick market by considering the effects of stock splits on the absolute tick size. We observe that the increase in small trades occurs only in those splits that increase the relative tick and decrease the tick-size simultaneously. Our findings suggest that small investors are attracted by stock splits that cause an absolute tick-size reduction, which are those with relatively lower transaction costs.JEL Classification: G19, G32, G35We thank two anonymous referees and the editor, J.M.

We explain in this work why a straight calibration to published input-output or SAM data in multisectoral modelling may lead to the use of an incorrect representation of the productive technology, hence casting doubts on the value of the empirical results. The culprit is the possible presence of indirect taxation in the form of, for instance, a value-added tax. We show how to unveil the hidden tax rates so as to clean up published data of this possibly distorting presence and therefore calibrate the correct production technology. This technology can then be used for multisectoral (i.e. CGE, input-output) analysis and simulations.  相似文献

In this paper, the random stochastic frontier model is used to estimate the technical efficiency of Japanese airports, with regulation and heterogeneity included in the variables. The airports are ranked according to their productivity for the period 1987–2005 and homogeneous and heterogeneous variables in the cost function are disentangled. Policy implications are derived.  相似文献

A multistage stochastic model to forecast surrender rates for life insurance and pension plans is proposed. Surrender rates are forecasted by means of Monte Carlo simulation after a sequence of GLM, ARMA-GARCH, and copula fitting is executed. The model is illustrated by applying it to age-specific time series of surrender rates derived from pension plans with annuity payments of a Brazilian insurer. In the GLM process, the only macroeconomic variable used as an explanatory variable is the Brazilian real short-term interest rate. The advantage of such a variable is that we can take future market expectation through the current term structure of interest rates. The GLM residuals of each age/gender group are then modeled by ARMA-GARCH processes to generate i.i.d. residuals. The dependence among these residuals is then modeled by multivariate Gaussian and Student's t copulas. To produce a conditional forecast on a stock market index, in our application we used the residuals of an ARMA-GARCH model fitted to the Brazilian stock market index (Ibovespa) returns, which generates one of the marginal distributions used in the dependence modeling through copulas. This strategy is adopted to explain the high and uncommon surrender rates observed during the recent economic crisis. After applying known simulation methods for elliptical copulas, we proceeded backwards to obtain the forecasted distributions of surrender rates by application, in the sequel, of ARMA-GARCH and GLM models. Additionally, our approach produced an algorithm able to simulate multivariate elliptical copulas conditioned on a marginal distribution. Using this algorithm, surrender rates can be simulated conditioned on stock index residuals (in our case, the residuals of the Ibovespa returns), which allows insurers and pension funds to simulate future surrender rates assuming a financial stress scenario with no need to predict the stock market index.  相似文献

Housing bubbles may result in deep crises that affect all economic systems. This study investigates how the recent housing bubble in Spain has affected earnings quality during the whole bubble. To this end, we use data on mostly private construction activity firms in Spain, that is, construction and real estate companies. Earnings quality is studied by means of the predictive ability of earnings, conservatism, discretionary accruals and real earnings management. The results indicate a progressive decrease in the quality of financial reporting as the bubble develops, as managers try to conceal an underlying downward trend. We further show that earnings quality continues to decline even after the bubble bursts. Overall, this contribution, together with those of other environments, may suggest that, in a bubble context, we have to take care of firms’ earnings quality even some years before the crisis comes to the fore.  相似文献

This study examines the effects of the firm's ownership concentration and its institutional environment on corporate debt maturity choices. As ownership concentration and debt maturity are alternative governance mechanisms, we theorize and investigate whether their association is influenced by country-level governance factors that enhance outside monitoring by minority shareholders and debtholders. Our investigation is based on a dataset of 50,599 firm-year observations from 38 countries. We use a propensity-score matching approach and find that the effect of ownership concentration on debt maturity is conditional to country-level governance attributes. Ownership concentration has a negative effect on debt maturity in countries where both shareholder protection and creditor rights are weak. Ownership concentration, however, tends to lengthen debt maturity as protection increases, and this positive effect on the length of debt maturity is stronger in countries enhancing protection towards debtholders (instead of shareholders). We also explore other characteristics of ownership structure, such as the identity and presence of controlling shareholders. These results corroborate the view that entrenched shareholders may use debt maturity opportunistically. Our study provides new insights into the interplay between firm- and country-level governance mechanisms and a deeper understanding of cross-country differences in the association between ownership structure and debt financing.  相似文献
