Optimal control theory is used to analyze buffer stock price stabilisation. Linear econometric models of the world cocoa and copper markets are estimated over the period 1956-75 and the simulated to determine the “systematic” price for each commodity—the price when stochastic sources of market variation are suppressed. Stabilization at this price reduces the instability of producer revenue and also increases total revenue for both commodities. However, the buffer stocks are expensive. Net costs over the period 1966-76 are estimated at $1.7 billion for cocoa and $0.9 billion for copper.  相似文献

The advent of “freely floating” exchange rates in the 1970's coincided with the emergence of what is known as “monetary” or “asset” models of exchange rate behavior where exchange ratesmove to equilibrate demand for stocks of monies. The fundamental monetary model assumes purchasing power parity holds in the long-run, and therefore exchange rates are determined by the same factors that determine relative prices, to wit, money stocks, real incomes, and nominal interest rates. Though early proponents of the monetary view clearly emphasized its long-run nature, empirical testing has by and large neglected this caveat. Thus a model developed for long-run equilibrium exchange rates has instead been tested many times over on short-run equilibrium rates. The latter require a distinct model of their own. This paper develops a short-run equilibrium exchange rate model based on deviations of the short-run exchange rate from its long-run equilibrium. The model differs in that all variables are cast in real terms. It also differs in that the monetary and current account exchange rate versions are shown to be subsets of the more general wealth/portfolio framework used here. The present model considers, in addition to stocks of monies, stocks of foreign assets, and stocks of domestic wealth.  相似文献

In the 1990s alone, four states elected third-party governors. Walter Hickel of Alaska and Lowell Weicker of Connecticut were elected in 1990. Maine elected Angus King in 1994. And Jesse Ventura was elected governor of Minnesota in 1998. In this article, I examine these four cases in an attempt to identify the factors that contribute to third-party electoral success. I apply two models to these cases. The first model, “alternative culture,” holds that certain voters—regardless of specific context—are predisposed to support alternative candidates. The second model, “institutional context,” looks at factors such as name recognition, resources, and access to media as explanations of third-party success. I find that except for the influence of “partisan independence,” there is little evidence to support the persistence of an alternative culture of third-party voting. Rather, these four cases are linked by a context particularly favorable to these alternative candidates.  相似文献

We approach the problem of Hungary's transformation from a partially centrally planned to a market-oriented economy with a cross-country comparison using two computable general equilibrium (CGE) models of Hungary, 1977 and 1986, and one of Austria, 1976. These three models represent a continuum of small open economies and allow a “quasidynamic” analysis using static CGE models. We examine two types of transformation issues: external (trade liberalization, import price reductions, and redirection of foreign trade; “Dutch Disease reversal”) and internal (decreases in subsidy levels). Overall, it is clear that with Hungary's borrowing constraints, liberalization should not be pursued in isolation; a change in the tax structure is necessary at the same time. The results for Austria indicate that liberalization brings smaller welfare improvements accompanied by smaller increases in the current account and government deficits.  相似文献

This paper constructs a short-run general equilibrium model for an LDC-type economy. Some key features are the possibility of excess capacity and the presence of quantitative restrictions on exports and imports. A rich variety of pricing possibilities for tradeable goods is allowed for, including “water in the tariff” as well as domestic prices exceeding world prices with binding import quotas.The model is used to analyze alternative responses to a foreign-exchange crisis. Import controls, devaluation and cuts in government expenditures are compared. We find that: i) import quotas can worsen the balance of trade, ii) rationing foreign exchange for noncompetitive imports is stagflationary, increasing prices even under excess capacity, iii) a devaluation has strong effects on income distribution, although output and employment expand, and iv) cuts in government spending are deflationary but the income distribution effects are neutral.  相似文献

The present paper attempts to analyze the dynamic multiplier effects of fiscal monetary policies for developed countries in a consistent framework of a global econometric model under both fixed and flexible exchange rate regimes. The paper first discusses the estimation of exchange rate functions for eight developed countries with special reference to “fundamentals” in economic performance such as international gaps in inflation, productivity, expected real rate of return, and so on. The results are then incorporated into the global model to derive and compare dynamic multipliers under both fixed and flexible exchange rate regimes. “Insulation effects” are observed in most cases in terms of both output and inflation, though this differs according to the country. Policy implications are discussed at the end.  相似文献

There has been little systematic assessment of the impact of globalization on armed conflict within states. Drawing from bargaining theories of conflict, we posit that the global marketplace functions as an “audience” that rewards or punishes the policy choices of states. Globalization, which connotes an increased exposure to this marketplace, increases the relevance of the “costs” that this “audience” may impose. These prospective costs thus encourage peace and stability, as states that are integrated into the global economy have more to lose by instigating and sustaining violent conflict within their borders. Employing a two-stage Heckman Model, we assess the impact of various facets of globalization, including access to information, trade, foreign investment and aid flows, on intrastate conflict within the developing countries for 1990–1996.  相似文献

This paper develops a Vector Error Correction (VEC) model and uses the recently developed technique of ‘generalized’ impulse response analysis to test the empirical relationships in the Colombian economy between coffee revenues and a set of macro variables. We find that coffee price (revenue) shocks have exerted an important influence on money growth, inflation, and real exchange rates, and the direction of these effects are in line with some of the predictions of traditional Dutch Disease type models. The major difference between our results and the results of Dutch Disease type models arise in the effects of coffee booms on real output. We find that in the time horizon of 5 years after the boom, real output has increased in response to the effects of the coffee boom. The finding that coffee booms can result in positive long-run output effects is an important finding since it contradicts the traditional conclusion of Dutch Disease type models which envision an adverse long-run effect on output. We also find that the long-run effect of coffee booms is to reduce both current account and government deficits. These results illustrate strikingly that the term “Dutch Disease” is an unfortunately pejorative term that obscures the fact that coffee booms need not be viewed as a “disease” but as an extraordinary opportunity to strengthen internal and external balances.  相似文献

Economists’ focus on institutions in explaining economic growth, while important, can obscure the significant role played by individual entrepreneurs and the process of entrepreneurship. The prevailing view of entrepreneurship in economics (which continues to shape prevailing public policies) centers on Schumpeter's famous concept of “creative destruction.” In the context of sustained high levels of economic growth, as in the recent American experience, I focus on a different feature of entrepreneurship—“nondestructive creation,” in which the uncoordinated contest of ideas and search for new applications of existing ideas generate growth. And this nondestructive creation should be analyzed and can be fostered.  相似文献

Renewalist Christian ministries espouse a “Health and Wealth” theology that is embraced by increasing numbers of believers. This study investigated leading renewalist ministries’ World Wide Web sites to assess their application of visual, operational, and informational enhancements to communicate social order. A content analysis revealed a communication of social order that is consistent with prosperity theology. Much emphasis is placed on the appearance and personality of the ministry leader. Almost no attention is paid to traditional Christian symbolism. Web sites claimed the value of inclusiveness, but offered little visual representation of children, senior adults, the poor, and people of color. Sites communicated the importance of regular financial donations and product purchases, but offered no encouragement for local church attendance. This research provides limited insight into some key unanswered scholarly questions about use of the Web by religious organizations, but more work is needed to investigate these issues in a broader context.  相似文献

This paper explores some quantitative dimensions of the interdependence of rich and poor regions in the context of the United Nations World Model. It extends the original work on that model in three ways: (1) by updating some of the key parameters and exogenous variables in the light of recent data; (2) by developing a “control” solution to be used as a point of reference in policy simulations; and (3) by exploring the sensitivities of each of two groups of regions— developed and developing—to changes in one another's growth rates. Goals of closing the income gap between developed and developing regions and of increasing income levels in the latter are discussed.  相似文献

The performances of two programming models and three “simple” investment rules, the benefit-cost ratio, internal rate of return, and present value to constrained cost ratio, are compared in solving a four-year capital rationing problem in a Latin American nation. The properties and advantages of the various approaches are discussed and policy conclusions are drawn. In addition, the effects of including project timing variants and political/ bureaucratic constraints are explored.  相似文献

The agricultural policy model of the trade-off between agricultural growth and land degradation that we have developed, with Sudan as an application, shares common features with the computable general equilibrium (CGE) models. The model is used to address two questions. First, what are the future prospects of a green gross domestic product (GDP), are there reasons for alarm or not, and to what extent? Secondly, which among the four policies of price incentives, property rights, poverty reduction, and human capital are more effective than the others? We show that the prospects of natural resource-friendly agricultural development in Sudan—a rising green GDP—are not promising in the medium run, but that, indeed, there is a range of effective policies and choices that could reduce the trade-off between economic growth and land degradation.  相似文献

This paper explores the sensitivity of multiplier estimates under three alternative assumptions about factor supply. For this purpose, we have used a general equilibrium model of Malaysia which allows endogenous determination of factor and output prices and which permits substitution in both production and demand in response to price. The structure of the model and three alternative factor supply assumptions under which the model can be solved are described. These alternative assumptions amount to alternative “closure rules.” The results of a general increase in demand as estimated under each of the alternative closures are then presented. Finally, we examine the results of two specific types of demand increase under each of the closure rules, focusing especially upon welfare related variables such as real household consumption levels.  相似文献

We simulate a phased increase in the U.S. investment rate using a translog production function with technical progress (disembodied and/or embodied). We assume there will be an absorption lag implying that factors are underutilized during the transition to a higher investment rate. We find that the “sacrifice time” (the time that elapses until consumption surpasses the value it would have had under the initial investment rate) is roughly nine years. Across alternative specifications, phase-in periods, and absorption lags, the sacrifice time varies from seven to 13 years, and is insensitive to the percentage increase in the investment rate. With a three-year phase-in of a 20 percent increase in the investment rate with a one-year absorption lag, the average “ecade gain” in output (the percentage gain at the end of a decade) is roughly 4 percent; the decade gain in consumption, 0 percent; the five-decade gain, 10 percent in output and 6 percent in consumption; and the “investment rate return” (the internal rate of return on a permanent increase in the investment rate), 13 percent.  相似文献

The intangible aspects of knowledge transfer in multinational corporations (MNCs) continue to be a crucial area of research in social science research and raise the issue of knowledge governance structures. The purpose of this conceptual note is twofold. Firstly, we believe that there is more than one governance structure for successful knowledge transfers and flows. We provide a typology of three governance structures: “exchange,” “entitlement,” “gifts.” Secondly, most MNCs will need to take advantage of all three or a combination of these three socially complex governance structures.  相似文献

Is Hyman Minsky's “Financial Instability Hypothesis” actually an interpretation of Keynes General Theory? Yes and no. Yes, they both describe an economy dominated by monetary forces in which employment and output dance to the expectations of financial players via speculation. But, no, they do not contain the same analytical structure. Keynes' theory specifies static positions of equilibrium. Minsky's analysis investigates the dynamic processes of the business cycle. Minsky's work might be viewed as the business cycle theory Keynes hinted at, but never completed.  相似文献

Factors affecting domestic violence against women in four Turkish cities (Adıyaman, Sivas, Denizli and Kırklareli) having different socioeconomic structures, are analyzed in this study. These factors consist of social, cultural, economic and psychological factors. In contrast to what we expected based on earlier literature, family income level has a positive relationship with violence. Logistic regression analysis also revealed that being a university graduate and having a personal income decreases the prevalence of violence as expected. However, working women and women with children are more prone to domestic violence. Again, there is a strong association between the neighborhood where the family lives and the incidence of violence. The extent of male dominance, as measured by the question “How are decisions taken in the family” is also associated with domestic violence: woman is less likely to be abused in households where decisions are taken collectively. Likewise, families where women have to get permission from the husband to carry out certain activities, have an increased incidence of suffering from husband's violence. Psychological factors, like being abused or having witnessed violence as a child, are also significantly correlated with domestic violence.  相似文献

During the past few years, the international agencies have been playing down economic growth as the main road to the elimination of poverty and emphasizing the role of asset and income redistribution. The latest reflection of this attitude is the so-called “basic needs” approach. This essay attempts to demonstrate that where economic growth has been sufficiently high and sustained, it has been a powerful means of alleviating poverty. Growth has not “failed”; there is simply not enough International agencies should be cautious in advocating redistribution, for the results .  相似文献

This paper examines the relationship between assimilation and discriminatory practices encountered by Hispanic-Americans. Theories of intergroup relations have typically assumed that as members of minority ethnic groups assimilate to a dominant group, they perceive and experience lower degrees of discrimination directed against them. In reviewing theories of majority–minority relations, we have called this the “assimilationist” model. This view has been opposed by some scholars who argue that as minority ethnics assimilate and become more knowledgeable of the larger society, they perceive and experience higher levels of discrimination against them and their group. We have termed this the “conflict model” of interethnic relations. Using data from the 2002 National Survey of Latinos, conducted by the Pew Hispanic Center, we test opposing hypotheses based on these two models. Our findings, while exploratory, largely support the assimilationist model, with a few contradictory results. We discuss these findings and their implications for understanding the current situation of Hispanics in the United States.  相似文献
