We look at two countries that have independent fundamentals, but share the same group of investors. Each country might face a self-fulfilling crisis: Agents withdrawing their investments fearing that others will. A crisis in one country reduces agents’ wealth. This makes them more averse to the strategic risk associated with the unknown behavior of other agents in the second country, increasing their incentive to withdraw their investments. Consequently, the probability of a crisis there increases. This generates a positive correlation between the returns in the two countries. Since diversification affects returns in our model, its welfare implications are non-trivial.  相似文献

This paper provides a rational expectations equilibrium framework to organize the following observations about the U.S. housing market from 1975 to 2007: (i) housing occupancy patterns were approximately constant, (ii) rents were stable, and (iii) house prices appreciated considerably in the late 1990s. I develop a model based on search and matching theory and close it by specifying a state of household confidence that is assumed to take one of two sunspot-driven values: normal or exuberant. The model generates a substantial increase in house prices and stable rents as the probability of the exuberant state increases, driven by self-fulfilling beliefs. I explore which aspects of the parameterization are important for generating a large appreciation in house prices in the model.  相似文献

Herding and contrarian behaviour are often-cited features of real-world financial markets. Theoretical models of continuous trading that study herding and contrarianism, however, usually do not allow traders to choose when to trade or to trade more than once. We present a large-scale experiment to explore these features within a tightly controlled laboratory environment. Herding and contrarianism are more pronounced than in comparable studies that do not allow traders to time their decisions. Traders with extreme information tend to trade earliest, followed by those with information conducive to contrarianism, while those with the theoretical potential to herd delay the most. A sizeable fraction of trades is clustered in time.  相似文献

Tobin's q, investment, and the endogenous adjustment of financial structure   总被引:1,自引:0,他引:1  
Should q theory be modified to take account of financial structure? This paper analyzes a general equilibrium q model where financial structure affects firm value. Agency costs and taxes combine to yield an interior solution for the endogenous debt–equity ratio. Although q is still a ‘sufficient statistic’ for investment, the endogenous adjustment of financial structure alters the relation between the interest rate and investment. In this model an increase in the corporate tax rate could either raise or lower the steady-state capital stock. Furthermore, both q and investment could jump in opposite directions to that of their steady-state values.  相似文献

Abstract.  We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we first fully characterize the spatial equilibria analytically. Comparing the equilibrium and the first-best, we secondly show that both organizational and spatial inefficiencies may arise. In particular, when fixed costs are low, when transport costs are high, and when products are close substitutes, the market outcome may well have to too many multinationals operating from a social point of view ('over-investment'). As a by-product, under-agglomeration of exporters in the larger market may arise.  相似文献

This paper is purported to analyze the consequences of liberalized economic policies on the skilled–unskilled wage inequality in the developing countries using a three sector general equilibrium model reasonable for at least a few developing economies. The analysis of the paper has found that the wage inequality rises unambiguously due to a reduction of import tariff from the low-skill manufacturing sector. However, an inflow of foreign capital produces a favourable effect on the wage inequality under a reasonable factor intensity condition. Interestingly, contrary to the common wisdom, a policy of labour market reform may raise the competitive unskilled wage and improve wage inequality under reasonable condition.  相似文献

This paper analyses the presence of financial constraint in the investment decisions of 367 Brazilian firms from 1997 to 2004, using a Bayesian econometric model with group-varying parameters. The motivation for this paper is the use of clustering techniques to group firms in a totally endogenous form. In order to classify the firms we used a hybrid clustering method, that is, hierarchical and non-hierarchical clustering techniques jointly. To estimate the parameters a Bayesian approach was considered. Prior distributions were assumed for the parameters, classifying the model in random or fixed effects. Ordinate predictive density criterion was used to select the model providing a better prediction. We tested thirty models and the better prediction considers the presence of 2 groups in the sample, assuming the fixed effect model with a Student t distribution with 20 degrees of freedom for the error. The results indicate robustness in the identification of financial constraint when the firms are classified by the clustering techniques.  相似文献

The evidence in this paper suggests that the q-theory of investment is not adequate to explain capital expenditure decisions at the firm level. Managerial as well as market perception is important, with the former more critical than the latter. The results also suggest that stock market activity has only limited implications for the resource allocation process in the economy. The evidence for the q-theory, based on firm-level data, confirms the previous finding in the literature that the poor empirical performance of the model in the past has been due in part to the use of aggregate data at the economy level. These findings have important implications for the debate in the literature regarding the relationship between shareholder myopia and managerial myopia. There is a notion in the literature that the stock market puts too much pressure on managers, who in turn indulge in myopic behaviour by underinvesting for the long-term, especially by way of R and D expenditures. The results presented here suggest that, given the limited role that market perception elements play in the determination of capital expenditures at the firm-level, shareholder myopia is unlikely to lead to managerial myopia.  相似文献

We test for price bubbles in 14 national real estate investment trust (REIT) markets, and measure the degree of their convergence towards a common trend. Our methodology consists of the recently developed test of Phillips, Shi and Yu (2014) for mildly explosive processes, and the Phillips and Sul (2007) method for modelling convergence among random variables. We find evidence of explosive behaviour in index levels of seven of the 14 markets. In contrast, explosive dynamics are found in only one price/dividend ratio. More than half of the episodes of explosive behaviour are date-stamped to periods prior to the 2007–2009 financial crisis. We also discover a number of periods over which the markets converge towards a common trend. Interestingly, all of the convergence intervals coincide either with periods of crisis, or with periods of market exuberance. For instance, evidence of convergence is found during the 2000 dot-com crash, the 2007–2009 subprime crisis and the 2010–2013 European sovereign debt crisis, as well as over the bubble period of 2004–2005.  相似文献

Private investment and financial development in a globalized world   总被引:1,自引:0,他引:1  
Using recently developed panel data techniques on data for 43 developing countries over the period 1970?C1998, this article provides an exhaustive analysis of causality between aggregate private investment and financial development. A common factor approach on annual data, allowing for global interdependence and heterogeneity across countries, suggests positive causal effects going in both directions. The finding has rich implications for the development of financial markets and the conduct of macroeconomic policies in developing countries in an integrated global economy.  相似文献

This study examined investment–cash flow sensitivity in unconstrained and constrained firms from 1980 to 2010 in a sample of Italian manufacturing firms. Investment sensitivity to cash flow decreased over time, and financially constrained firms showed little difference in the decline compared with unconstrained firms. Last, investment sensitivity to cash flow increased during the financial crisis of 2008.  相似文献

This article proposes a decision-making model that assesses the different aspects associated to Social Venture Capital (SVC) investment decisions. SVC companies buy shares of investee companies, valued according to financial and social aspects. The proposed model includes three main factors: the previous experience with the company (the past); its financial information and intangible assets (the present); and the proposed project, considering financial and social criteria (the future). The model has 26 criteria and 160 indicators, prioritized by means of Analytic Hierarchy Process (AHP). AHP simplifies a complex problem using a hierarchical analysis methodology, which enables subjective judgements among different criteria. The model has been tested in a given SVC company. Its development is explained in this article.  相似文献

A real options market model is developed, which derives the firms' optimal investment and disinvestment thresholds simultaneously in a competitive environment. It combines genetic algorithms and stochastic simulation, whereby vast modelling flexibility is gained. For example, different market interventions can be integrated and their effects on the firms' investment behaviour and the sectoral welfare can be assessed. The model is validated for its application to competitive markets by numerically replicating the optimality property of myopic planning. According to the results, production ceilings and investment subsidies are preferable to price floors because the welfare is less reduced for a given stimulation of the willingness to invest. Moreover, it is shown that not considering disinvestment options, which in reality often exist, can lead to incorrect valuations of investment strategies at firm level and incorrect policy impact analyses at macroeconomic level.  相似文献

Abstract We characterize the optimal financial structure as a strategic device to optimize the value of a firm competing in a market where entry is endogenous. Debt financing is always optimal under quantity competition, and, contrary to the Brander‐Lewis‐Showalter results based on duopolies, we show the optimality of moderate debt financing also under price competition with cost uncertainty (but not with demand uncertainty). We derive the formulas for the optimal financial structure, which does not affect the strategies of the other firms but reduces their number.  相似文献

The paper develops a typological framework of the roles of state investment banks (SIBs) in the economy. The typology identifies four different roles: countercyclical; developmental; venture capitalist; and challenge-led. The paper conceptually elaborates the typology by first providing a historical overview of SIBs, and then discussing how the mainstream “market failure theory” justifies them. It then advances a different conceptualization based on insights from heterodox economics, showing that all roles of SIBs are more about market creating/shaping rather than market-failure fixing. The paper concludes with a proposal of a new agenda for research on SIBs based on our typological framework.  相似文献

While the aggregate effects of sudden stops and international financial crises are well known, the disaggregated channels through which they work are not well explored yet. In this paper, using job flows from a sectoral panel dataset for four Latin American countries, we find that sudden stops are characterized as periods of lower job creation and increased job destruction. Moreover, these effects are heterogeneous across sectors: we find that when a sudden stop occurs, sectors with higher dependence on external financing experience lower job creation. In turn, sectors with higher liquidity needs experience significantly larger job destruction. This evidence is consistent with the idea that dependence on external financing affects mainly the creation margin and that exposure to liquidity conditions affects mainly the destruction margin. Overall, our results provide evidence of financial frictions being an important transmission channel of sudden stops and in the restructuring process in general.  相似文献

A positive equilibrium price of size exists when size is a scarce productive resource. This paper articulates a costly-state-verification model of financial contracting with heterogeneous lender sizes. We find that in a non-rationing direct lending equilibrium, (1) Financial contract is nonlinear in that expected rates of return on loans increase with loan sizes; (2) Endogenous asset indivisibility arises; (3) The total social surplus under a nonlinear contract is less than that under a linear structure; (4) Average debt size affects the market value of a firm. We also extend analysis to the case of credit rationing and financial intermediation.I thank James A.
