摘要：This paper studies consumption and saving decisions over time in a life cycle model in which survival from one period to the next is endogenous. Survival probabilities depend on health, which is a capital stock subject to depreciation and which can be augmented by consumption (nutrition). Borrowing is ruled out in our model and we investigate optimal consumption decisions when income fluctuates at seasonal frequencies and when income follows a stochastic process. Among other results, we show t...

摘要：Various risk sharing arrangements are common in underdeveloped agrarian economies where households have no formal means of contract enforcement and little access to risk markets. Social insurance is still possible through repeated interaction in an environment with few informational asymmetries. In a simple repeated game model of two self-interested households facing independent income streams, we characterize the best arrangement that can be sustained as a noncooperative equilibrium. We estab...

摘要：Capital, labor, human capital and technical progress are the four principal sources of growth of aggregate real output. Based on data from individual Brazilian states in 1970 and 1980, an aggregate meta-production function relating aggregate real output of each state to capital, labor, average education and time is estimated. It is found that one additional year of average-education per person of the labor force increases real output by approximately 20 percent However, there is also evidence ...

摘要：Most measures of the real effective exchange rate (REER) do not capture the complex ways in which the structure and direction of trade adapt to changes in exchange rates. Conventional measures of the REER are based on the stringent assumptions that cross price elasticities with respect to exports of third party competitors are all zero and with respect to trading partners they are all equal. This paper develops an alternative index of competitiveness that captures the effects of a whole set of...

摘要：This paper focusses on the potentially important role of rural nonagricultural activity in the development process. Using the Hymer-Resnick Z-goods model as a point of departure, we first show that its pessimistic conclusions are based on rather restrictive assumptions as applied to the colonial period. We relax these assumptions, indicating the theoretical possibility of a substantially more positive scenario for that period. Subsequently, we analyze the role of Z-goods, traditional and nontr...

摘要：This paper introduces distributional activities in one of the simplest endogenous growth models. Firms engage in investment and lobbying, with the extent of the latter determining the number of restrictive regulations in force. As a result, the growth rate increases with the private cost of passing a regulation, while dynamics include rise and decline, as in Olson's theory. The empirical evidence is from Uruguay, a relatively wealthy country that has dramatically lagged behind. It shows that r...

摘要：Our ultimate objective is to enhance the standard of living of our societies. But the standard of living has different meanings for different people. A thorough investigation of the concept of the standard of living has been made only recently by Sen, who defines it in terms of functioning and capabilities. Functioning is an achievement, whereas capability is the ability to achieve. The main objective of the present paper is to compare achievements (levels) and improvement (changes) in the sta...

摘要：This research analyzes longitudinal data from the Philippines based on a sample of over 3,000 mother-infant pairs covering a period from the mother's pregnancy until the age two. The econometric methods alleviate problems, including unobserved heterogeneity and endogeneity of important explanatory factors, and exploit the longitudinal nature of the data set. The results indicate that a group of individual, household, and community factors importantly affect the outputs of the child health prod...

摘要：This paper is a case study of the investment (planting) decisions in the Bahia cocoa sector in the period 1966-1985, with a special focus on the role of producer prices and investment subsidies. The study deals separately with replanting decisions and new planting decisions using aggregate time series data and exploits several concepts of vintage production models. The results of the analysis show that the dynamic response of replanting and new planting to changes in profitability and to inter...

摘要：The relation between parental characteristics, community characteristics and child height is examined using Brazilian household survey data, matched with information collected at the municipio level. Child height is significantly affected by local infrastructure, particularly the availability of modem sewerage, piped water and electricity. Higher sugar and dairy prices are associated with lower child height, although mothers with at least elementary schooling are able to counteract the deleter...
