We propose an optimal filter to transform the Conference Board Composite Leading Index (CLI) into recession probabilities in the US economy. We also analyse the CLI's accuracy at anticipating US output growth. We compare the predictive performance of linear, VAR extensions of smooth transition regression and switching regimes, probit, non‐parametric models and conclude that a combination of the switching regimes and non‐parametric forecasts is the best strategy at predicting both the NBER business cycle schedule and GDP growth. This confirms the usefulness of CLI, even in a real‐time analysis. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

A new framework is presented for the study of the existence and uniqueness of solutions to the Koopmans’ equation in the unbounded case, that is based on the contraction mapping approach. In the bounded below case with bounded consumption streams, uniqueness of the solution in the whole class of weak-star continuous utility functions is obtained. When the aggregator is unbounded below and/or consumption streams are unbounded, existence of a weak-star continuous solution is shown, and a simple criterium to check the sufficient conditions for existence is provided.

Summary. The traditional model of sequential decision making, for instance, in extensive form games, is a tree. Most texts define a tree as a connected directed graph without loops and a distinguished node, called the root. But an abstract graph is not a domain for decision theory. Decision theory perceives of acts as functions from states to consequences. Sequential decisions, accordingly, get conceptualized by mappings from sets of states to sets of consequences. Thus, the question arises whether a natural definition of a tree can be given, where nodes are sets of states. We show that, indeed, trees can be defined as specific collections of sets. Without loss of generality the elements of these sets can be interpreted as representing plays. Therefore, the elements can serve as states and consequences at the same time.Received: 23 January 2003, Revised: 2 November 2003, JEL Classification Numbers: C72, D70.

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification.  相似文献

The purpose of this paper is tostudy how the choice of environmental standardsby governments is affected by the existence ofwage incomes when firms locations areendogenous. In developed countries labor isunionized, which allows positive wage incomesto arise. Thus, each government has incentivesto persuade firms to locate in its countrysince social welfare depends on suchincomes. But, as pollution damages theenvironment, each government will only try toattract polluting firms to thecountry, to obtain the wage incomes, whenthe valuation of environmental damage showsthat it is low.  相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling   总被引:1,自引:0,他引:1  
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework.  相似文献

The American corporate financing system, unlike that of most other countries, has not been organized around a set of “universal banks” that perform a variety of functions for their clients. Indeed, the distinguishing feature of American financial history is the number and variety of financial intermediaries, and their relationships with corporations (and one another). Besides commercial banks, there are investment banks, insurance companies, venture capitalists, commercial paper dealers, mutual funds, and many others. The economic role of such intermediaries is to reduce market frictions such as “asymmetric information” and “agency problems” that otherwise raise the cost of outside capital for U.S. companies. This article views the changing menu of such intermediaries and their networks as the driving force behind the evolution of American corporate finance. U.S. financial history is seen as a series of institutional and financial innovations designed in large part to work around costly restrictions on relationships–particularly, limits on the scale and scope of U.S. banks–that do not exist in most other countries. In terms of its success in reducing the information and control costs of corporate finance, the history of the American financial system includes periods of significant progress as well as major reversals. Three relatively successful periods– the early 19th-century in New England, the “incipient” universal banking of the 1920s, and modernday financial capitalism–are separated by periods of drastic reductions in the menu of financial relationships– particularly the Great Depression and its 20-year aftermath. Besides new financial claims like preferred stock and new intermediaries such as venture capitalists, another important innovation is new forms of cooperation among intermediaries– especially among banks, venture capitalists, trusts, pensions, and investment banks–that have enabled the U.S. financial system to provide some of the key advantages of universal banking systems. Some of the largest U.S. commercial banks today can be viewed as positioning themselves to play a central coordinating role in these new coalitions of intermediaries. In so doing, they may become the platform for a distinctively American universal banking system.  相似文献

Price bubbles provide a unique opportunity to study the financial acumen of shareholders. We focus on the 1720 South Sea episode as experienced by the Royal African Company whose stock was more speculative than other joint stocks. During 1720 the company had a new large stock issue. This paper examines the financial acumen of those women who traded senior and engrafted stock across 1720. We find that depending on the pricing regime, these women at worst broke even on their activities or had positive speculative gains. Our findings are consistent with a growing literature on the positive link between gender, capital gains and financial markets.  相似文献

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated.  相似文献

Enterprise risk management (ERM) is a process that manages all risks in an integrated, holistic fashion by controlling and coordinating any offsetting risks across the enterprise. This research investigates whether the adoption of the ERM approach affects firms' cost of equity capital. We restrict our analysis to the U.S. insurance industry to control for unobservable differences in business models and risk exposures across industries. We simultaneously model firms' adoption of ERM and the effect of ERM on the cost of capital. We find that ERM adoption significantly reduces firm's cost of capital. Our results suggest that cost of capital benefits are one answer to the question how ERM can create value.  相似文献
