Price and quantity adjustment in a dynamic closed model: The dual stability theorem

The paper analyzes dual instability in a dynamic input-output framework. It is divided into three parts: the first gives an informal introduction, the second discusses the similarity with the knife edge, and the last suggests a new interpretation, which guarantees nonnegative solutions and relative stability. It has been assumed that the producers adjust their prices following an adaptive expectation mechanism, and the current level of investment to the expected value defined by a golden rule approach.     

The value of money in a dynamic equilibrium model

Summary. This paper studies the pricing of money in an infinite-horizon economy with heterogeneous agents, incomplete financial markets and arbitrary borrowing restrictions. Purchases of the consumption good are subject to a cash-in-advance constraint. Under general conditions I show that the price of money is equal to its fundamental value, where this value is defined over all state-price processes that are compatible with the existence of no-arbitrage opportunities. This equality implies that the cash-in-advance constraint is binding infinitely often for all agents in the economy. The analysis highlights certain differences in the determination of the price of money with respect to models with money in the utility function that bear on the optimal implementation of economic policies.Received: 23 October 2003, Revised: 26 August 2004 JEL Classification Numbers: D52, E44, G12.M.S.

Nonlinearity in dynamic adjustment: Semiparametric estimation of panel labor supply

We estimate a semiparametric dynamic panel data model by the local linear kernel method and we interpret the slope of the nonparametric component function as a varying slope coefficient. Thus, the slope coefficient is a smooth, but otherwise unknown, function of some of the regressors. A Monte Carlo experiment is reported to examine the finite sample performance of the local linear estimator. We apply the estimation method to a labor supply equation for men from the triannual Survey of Income and Program Participation (SIPP). Specification tests based on the estimated labor supply elasticities, partial adjustment coefficients, and residuals demonstrate the improvements from a semiparametric partially linear model. Our empirical results point to a need by economists to revisit the issue of the speed of labor market adjustment to policy induced shifts in labor demand and to take more formal econometric account of heterogeneity in wage effects when studying the distributional consequences of tax reforms for labor supply earnings.

Demographic processes in a model of innovation diffusion with dynamic market

In this paper we study a binomial innovation diffusion model for a variable size market by modelling the demographic process of entrance-exit from each market compartment. We examine from a theoretical point of view the effect of the simultaneous presence of economic and demographic parameters under the exponential market growth hypothesis, by presenting some general results on the adoptions and sales time path. We also enlighten the relevance of considering these variables in relative terms and show how, in presence of a dynamic, the diffusion process never saturates the market. Finally, we test our model on a data set for cellular phones market in different countries.     

Gradualism and dynamic trade adjustment: Revisiting the pro-trade effect of free trade agreements

Do pro-trade effects of free trade agreements reflect timing of policy or dynamic trade adjustment? Only the latter involves dynamic welfare gains. I find that dynamic trade adjustment is as important as the immediate impact effect of free trade agreements.     

The dynamic impact of intellectual capital on firm value: evidence from China

We examine the dynamic relationship between intellectual capital (measured by human capital and organizational capital) and firm value of Chinese listed firms. We do causality identification using system GMM and IV estimation, and find no significant relation between human capital and firm value, but organizational capital positively affects firm value with a lag. Our findings are robust to firms with different property rights, of different sizes, or in different industries, with the only exception of capital-intensive firms, in which human capital has a significant influence on firm value. The results imply that the improvement of organizational system plays a more important role in raising the value of a firm in a typical developing country, like China.     

The use of knowledge in technology entrepreneurship: A theoretical foundation

While technology entrepreneurship has been widely recognized as a driver of economic growth, there exists little in the way of a unified framework for understanding technology entrepreneurship and assessing its value proposition, particularly when network externalities and information are involved. In this paper we bring together several strands of literature and identify the components that form a foundation for understanding modern technology entrepreneurship. In particular, technology functions as a capital good that embodies knowledge about performing productive tasks, and the value of this knowledge depends on how well it is able to utilize decentralized local knowledge and spontaneous orders.     

France in the global economy: a structural approximate dynamic factor model analysis

This study identifies the main shocks that cause fluctuations in French output and their channels of transmission. It uses a large-dimensional structural approximate dynamic factor model. There are three main findings. First, common shocks, especially demand shocks, which seem to originate from the U.S., play an important role in explaining French economic activity. While international trade, relative prices, and foreign direct investment (FDI) flows are the main channels of transmission, the stock market, consumer confidence, and interest rates also matter. Second, France’s integration with the rest of the world has increased over time. Third, there is some tentative evidence of regional components in explaining French output fluctuations; country-specific components also contribute. The predominance of exogenous factors affecting French output, the asymmetry in the transmission of shocks, and France’s participation in a currency area argue for making French goods, services, and labor markets as flexible as possible.     

Forecasting the probability of US recessions: a Probit and dynamic factor modelling approach

Abstract Quantifying the probability of U.S. recessions has become increasingly important since August 2007. In a data‐rich environment, this paper is the first to apply a Probit model to common factors extracted from a large set of explanatory variables to model and forecast recession probability. The results show the advantages of the proposed approach over many existing models. Simulated real‐time analysis captures all recessions since 1980. The proposed model also detects a significant jump in the next six‐month recession probability based on data up to November 2007, one year before the formal declaration of the recent recession by the NBER.     

The dynamics of entrepreneurship: hysteresis, business cycles and government policy

This article estimates two unobserved components models to explore the macrodynamics of entrepreneurship in Spain and the USA. We ask whether entrepreneurship exhibits hysteresis, defined as a macrodynamic structure in which the cyclical component of entrepreneurship has persistent effects on the natural rate of entrepreneurship. We find evidence of hysteresis in Spain, but not the USA, while in Spain business cycle output variations significantly affect future rates of entrepreneurship. The article discusses implications of the findings for the design of entrepreneurship policies.     

Knowledge-intensive entrepreneurship: sectoral patterns in a sample of European high-tech firms

This paper studies the relative importance of prior knowledge and resources available to a startup at the time of its founding across technologies. Our analysis is based on a survey submitted to the founders of new innovative ventures patenting in the biotech, electronics and medical devices technologies. Our findings show that pre-entry knowledge about customers’ needs and characteristics, about the technology and about potential suppliers and competitors differentially affect the technological and market entrepreneurial choice of the surveyed firms. These results suggest the existence of patterns of entrepreneurial activities that are technology-specific.     

Decomposing household,professional and market forecasts on inflation: a dynamic factor model analysis

A dynamic factor model with stochastic volatility is used to investigate the relationships between three alternative measures of inflation expectations. The results show evidence of both a common time-varying trend and a common transitory component between inflation and short-term inflation expectations from households, professionals and markets. While the common time-varying trend has declined in both level and volatility since the early 1980s, it was found that consumer expectations are disproportionately influenced by the visibility of prices of select few goods. Roughly speaking, a 1% point increase in food and energy prices leads to about 1/3% point increase in consumer forecasts of inflation. In terms of policymaking, this finding suggests that stability in highly visible prices can moderate inflation in a meaningful way.     

Measuring business cycle comovements in Europe: Evidence from a dynamic factor model with time-varying parameters

Estimation results from a dynamic factor model confirm an increase in output synchronization across European countries during the run-up to the inception of EMU, but EMU by itself has not continued to foster the emergence of a common business cycle.     

The government's time discount rate: Choices and consequences in a dynamic framework

This paper considers a closed macroeconomy where the monetary authority pursues an inflation target and policy outcomes are the consequence of a Nash game between fiscal and monetary authorities. The specification of the macroeconomic framework is characterized by nonlinearities which lead to multiple equilibria with differing stability properties. Employing a calibrated model and simulations derived using the Mathematica package, the stability properties of the economy and the likely choice of equilibrium are examined. Within this framework, the dynamic consequences of different time discount rates for the fiscal authority are investigated, both in a world of certainty and also in a world of uncertainty. It is shown that, in a world of certainty, it will be optimal to choose the fiscal authority's time discount rate equal to the market rate of interest. However, depending on the degree of uncertainty in evaluating the time discount rates of consumers and of the fiscal authority, it may be appropriate to bias the fiscal authority's discount rate above or below the expected interest rate.     

暂定金额、点工与价格调整

暂定金额暂定金额(ＰｒｏｖｉｓｉｏｎａｌＳｕｍｓ)和不可预见费(Ｃｏｎｔｉｎｇｅｎｃｙ)都是ＦＩＤＩＣ合同第５８款中的内容,其中还包括了按点工(Ｄａｙｗｏｒｋ)的标准发出工程变更令。乍看起来,“暂定金额”的英文及中译文都有些令人费解,其实它有些类似我们国内所讲的“备用金”的概念,它与工程变更令的关系相当密切。按照咨询工程师的工程变更令或其他指示暂定金额可以部分使用,或者全部用完,甚至还会出现额外追加的情况。在项目实施时一点都不动用暂定金额只能是理论上的期望。暂定金额的表现方式因情况而异:有些暂定金额是业主在…     

The acquisition of information in a dynamic market

Summary This paper models the information acquisition process in an intertemporal rational expectations framework. It demonstrates that equilibria do not generally exist in intertemporal economies in which agents are assumed to know the state-contingent price path and the information acquisition process is endogenous. In addition, an example of a fully revealing equilibrium in which agents pay a strictly positive amount for information is provided. Finally, we also show that it is possible for an equilibrium to exist in which agents choose to purchase information even if all agents, including the agents who purchased the information, are made strictly worse off by the purchase.The author would like to thank Kerry Back, Gerry Feltham Rich Kihlstrom, Vasant Naik, Bryan Routledge, Harald Uhlig and Josef Zechner for their comments and suggestions.

The interrelations between legal and economic processes: a consideration of the reactions

The responses to my 1972 article on the interrelations between legal and economic processes are summarized and critiqued. The principal authors are James Buchanan, Peter Boettke, and William Fischell. My replies center on the normative character of their proposed alternative interpretations vis-à-vis my strictly positive approach. My positivist approach considers law as made rather than found; that law is not something transcendental and given but a matter of human social choice through pragmatic processes; that belief system and material interest influence law making and the law that is made influences belief system and material interests. The article thus is a defense of undertaking an objective, positivist analysis of law and government as they exist in actual political economies (legal-economic nexuses).

The impact of financial liberalization on capital structure adjustment in Pakistan: a doubly censored modelling

The purpose of the study is to explain adjustment rate towards target capital structure of Pakistani nonfinancial listed firms and to investigate the impact of financial liberalization (FL) on capital structure adjustment rate. We control for the unobserved heterogeneity and the fractional nature of adjustment rate by applying an unbiased dynamic panel fractional estimator on an unbalanced panel data of Pakistani nonfinancial firms listed during 1972–2010. We find that these firms adjust at an annual rate of 24–51% to reach their capital structure targets. We argue that in order to optimize the benefits of FL the government should strengthen financial as well as judicial institutions to enforce the creditors’ rights that will enable access to more options to Pakistani firms to raise cheaper external financing.     

The age-dependent value of time: a life cycle analysis

A life cycle framework is developed to examine how the value of time (VOT) changes as one ages. We consider two risk-sharing schemes, the Tonti scheme under which wealth is actuarially insured, and the Robinson Crusoe scheme under which insurance institution is entirely absent. For the first time in the literature, we characterize the condition, in terms of key parameters for valuating VOT, under which VOT may increase, decline, or even display more complicated profiles, as one ages. Our analysis reveals the crucial role played by the relative magnitude of the market interest rate to other parameters (including the parameter of time preference, the age-specific mortality and the wage growth rate) in determining the age profile of VOT, and the difference in VOT that is caused by the insurance scheme.
