We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods. 相似文献

This article analyses the consequences of the money supply growth rate on capital intensity and economic growth in an overlapping-generations model with real balances entering the production function. Within this theoretical framework, anticipated inflation generates an ambiguous effect on capital–labour ratio, because two forces work simultaneously in opposite directions: one driving towards a pure Tobin effect (due to the OLG demographic structure of the economy) and the other pushing down the capital stock (due to the productive role of real balances). Despite the unclear effects exerted on capital intensity, higher monetary growth rates unambiguously reduce real money demand, consumption, total wealth and welfare. 相似文献

In this paper, we test whether European consumers are addictive smokers and, if this is the case, then whether such addictions can be explained by the rational addiction theory. To this end, we start from a non‐separable intertemporal utility function, which allows us to derive a demand function that is estimated using tobacco time‐series. The results are in accordance with the model of rational addiction for all European smokers. Thus, we observe the addictive character of tobacco consumption and, secondly, we note that the addiction is not the result of myopic consumer behaviour, but rather of the maximization of total utility, implying that consumers consider the future effects of their current decisions. 相似文献

In spite of the increase in domestic law enforcement policies in the U.S. drug related crime has followed a non-monotonic
trend and cocaine and heroin prices, instead of increasing, have been dropping or remained stable over time. All this in a
context of an increase in these drugs’ consumption during the 1980s and a small decrease during the 1990s. This paper provides
an explanation to these counter-intuitive effects of domestic law enforcement policies. We model how drug lords respond to
this type of policy within a conflict framework over the control of distribution activities for illegal drugs, which is novel.
The model predicts drug distribution activities, drug prices and drug consumption. These predictions appear to be consistent
with the empirical evidence in the United States. 相似文献

Dubey and Geanakoplos (Q J Econ 117:1529–1570, 2002) have developed a theory of competitive pooling, which incorporates adverse
selection and signaling into general equilibrium. By recasting the Rothschild–Stiglitz model of insurance in this framework,
they find that a separating equilibrium always exists and is unique.
We prove that their uniqueness result is not a consequence of the framework, but rather of their definition of refined equilibria.
When other types of perturbations are used, the model allows for many pooling allocations to be supported as such: in particular,
this is the case for pooling allocations that Pareto dominate the separating equilibrium. 相似文献

A home firm signals her private cost information by expanding in a foreign firm’s country. Credible signaling to deter counter‐entry may occur through a direct investment (but not through exports), and may even entail entering an unprofitable market. While this produces social benefits, uninformative signaling may be welfare‐reducing. Hence, we argue that moderate to high location costs may be socially desirable. We also show that there are not simple monotonic relationships between technology/demand conditions and firms’ entry modes. Thus, the signaling interpretation of international expansion makes it possible to explain some controversial empirical findings on a theoretical ground. 相似文献

In recent years there has been a surge in mergers and acquisitions (M&As) in all sectors of economic activity. Cross-border operations have followed this trend, creating global companies operating in all major world markets. In this paper we study the pattern of cross-border M&As in the banking industry relative to the non-financial sector of the economy and investigate which factors make it more likely that a bank will expand its activities abroad. We find that cross-border M&As are rarer in banking than in other sectors, possibly owing to the importance of information asymmetries in banking relationships and to regulatory restrictions. Using data on almost 2500 banks from 29 OECD countries, we also show that the most significant features of banks with foreign equity interests relate to efficiency: banks with cross-border shareholdings are on average larger, more profitable, and based in countries with a more highly developed banking market. 相似文献

The strategic analysis of the private provision of a discrete public good has shown the existence of multiple Nash equilibria with the efficient number of players voluntarily contributing. However the coordination issue is left unexplained by this literature. The experimental evidence shows that communication among players is helpful in achieving cooperation. We claim that, from the theoretical point of view, this is equivalent to playing correlated equilibria in an extended public good game with communication, modeled as Chicken. We characterize such equilibria as feasible coordination mechanisms to achieve public goods provision in the general contribution game. We further introduce a second kind of game characterized by payoff externalities that may persist after the minimal threshold of contributors is achieved. While it is easy to show the existence of Pareto efficient correlated equilibria in the first game, in the second one players face incentive problems such that a first best cannot always be an equilibrium. Nevertheless there exist correlated equilibria that can qualify as incentive efficient mechanisms, once free riding is seen as a moral hazard issue. Finally, with an example, we discuss the impact of coalition formation in our framework. 相似文献

Evaluation of drought management in irrigated areas 总被引:4,自引:0,他引:4
This paper focuses on the economic consequences of droughts for the irrigation sector. We develop a dynamic‐recursive mathematical programming farm model that assumes imperfect mobility of capital and labour as well as rational expectations about future water availability. The model is calibrated to 12 representative farms belonging to three irrigation communities of the Guadalquivir Basin (south Spain) and used to simulate the 1991–1997 period, which included 3 years of intense drought. Results indicate that the drought imposed significant costs on farmers, but show also that water managers partly exacerbated these costs by allocating excessive amounts of water to irrigators in the abundant years. The model is also used to evaluate the benefits of a perfect water supply forecast and to simulate the economic gains of a voluntary water banking scheme. Results show that the benefits resulting from the perfect forecast of water supply 1 year ahead would represent a relative gain of 5%. However, a voluntary banking system would allow farmers to increase their benefits by 32–82% depending on the supply system. 相似文献

Technological resources in the form of patents, trade secrets, and know‐how have become key assets for modern enterprises. This paper addresses a critical issue in technology and innovation management, namely, the commercial exploitation of technological resources resulting from research and development (R&D) investments. Extracting economic value from these resources by maximizing the benefits for shareholders is an extremely challenging task because technological resources are intangible, idiosyncratic, uncertain, predominantly tacit, and with poorly defined property rights. In their attempt to extract the maximum value from their technological resources, firms increasingly combine their internal exploitation through new product development (NPD) with external exploitation through licensing. However, most existing studies on NPD and technology licensing have treated the two exploitation paths independently and in isolation, which has resulted in two separate research streams using different theories and addressing different managerial challenges. The purpose of this paper is to contribute to filling this gap by developing and testing a comprehensive conceptual framework that simultaneously considers the antecedents affecting the successful implementation of NPD and licensing strategies as well as their consequences on firm profitability. The paper in particular investigates the effects of the interplay between technological resources and three types of complementary resources, marketing, manufacturing, and relational. We test the model using structural equation modeling on a sample of 733 Spanish manufacturing firms observed from 2003 to 2007. The data provide support for the existence of different paths to market firm technologies: an internal path, whereby the ownership of technological resources fully explains NPD performance, and an external path, whereby high intensity of marketing and relational resources reinforces the positive effect of technological resources on licensing performance. This sustains the relevance of the resource‐based value‐enhancing effects of complementary resources in licensing, as opposed to the motivation‐reducing effects advanced by transaction cost‐based literature. Moreover, the empirical analysis shows a substitution effect between NPD and licensing, whereby their simultaneous pursuit at intense levels is associated with lower profit margins. This provides evidence of the much theorized, but seldom tested, rent dissipation effect. These findings offer several contributions to research on licensing, NPD, open innovation, and the resource‐based view of the firm. On a managerial level, they suggest that achieving maximum value from proprietary technologies may not entail exploiting them both through external and internal paths. Managers are also informed that the resource combinations that enhance licensing performance include marketing and relational resources. 相似文献
