This paper embeds product market search in an Ak growth model to study the effects of search frictions on market structure, capital accumulation, and long-run growth. The basic hypothesis is that search frictions, in giving rise to market power, result in higher prices and lower output levels. The falling demand for capital stemming from firms cutting back output then lowers the interest rate, dampening capital accumulation and slowing down growth. A decline in search frictions sets the process in reverse, eventually speeding up growth through the change in market structure. In the meantime, the stock market values of firms could fall. 相似文献

In this paper, we explore the role of labor markets for monetary policy in the euro area in a New Keynesian model in which labor markets are characterized by search and matching frictions. We first investigate to which extent a more flexible labor market would alter the business cycle behavior and the transmission of monetary policy. We find that while a lower degree of wage rigidity makes monetary policy more effective, i.e. a monetary policy shock transmits faster onto inflation, the importance of other labor market rigidities for the transmission of shocks is rather limited. Second, having estimated the model by Bayesian techniques we analyze to which extent labor market shocks, such as disturbances in the vacancy posting process, shocks to the separation rate and variations in bargaining power are important determinants of business cycle fluctuations. Our results point primarily towards disturbances in the bargaining process as a significant contributor to inflation and output fluctuations. In sum, the paper supports current central bank practice which appears to put considerable effort into monitoring euro area wage dynamics and which appears to treat some of the other labor market information as less important for monetary policy. 相似文献

We develop a search-matching model with rural-urban migration and an explicit land market. Wages, job creation, urban housing prices are endogenous and we characterize the steady-state equilibrium. We then consider three different policies: a transportation policy that improves the public transport system in the city, an entry-cost policy that encourages investment in the city and a restricting-migration policy that imposes some costs on migrants. We show that all these policies can increase urban employment but the transportation policy has much more drastic effects. This is because a decrease in commuting costs has both a direct positive effect on land rents, which discourages migrants to move to the city, and a direct negative effect on urban wages, which reduces job creation and thus migration. When these two effects are combined with search frictions, the interactions between the land and the labor markets have amplifying positive effects on urban employment. Thus, improving the transport infrastructure in cities can increase urban employment despite the induced migration from rural areas. 相似文献

What accounts for the significant real effects of monetary policy shocks? And what accounts for the persistent and hump shaped responses of output and inflation in response to such shocks? These questions are investigated in a model that incorporates labor market search, habit persistence, sticky prices, and policy inertia. While habit persistence and price stickiness are important for the hump shaped output response and the long, drawn out inflation response, respectively, labor market frictions increase the output response and reduce the inflation response relative to an otherwise similar model based on a Walrasian labor market. Significantly, policy inertia itself is found to be the most important factor in accounting for the magnitude of the output effects of policy shocks in the model. 相似文献

Standard models of labor adjustment assume that firms can change only the size of their workforce (the extensive margin) and not the number of hours of their existing employees (the intensive margin) in response to shocks. I propose a general equilibrium search model that allows for adjustment on both of these margins. The model includes on‐the‐job search that generates different vacancy filling and attrition rates across firms. I calibrate the model to a unique matched employer–employee panel of Danish firms and simulate two labor market policies aimed at promoting job creation: hiring subsidies and a reduction in the official workweek. 相似文献

I document that workers in newly tradable service occupations possess more occupation-specific human capital and are more highly educated than workers in previously tradable occupations. Motivated by this observation, I develop a dynamic equilibrium model with labor market frictions and specific human capital to study the labor adjustment process after a trade shock. When calibrated to match the increase in U.S. trade between 1990 and 2010, the model suggests that (1) output increases immediately after a trade shock and converges quickly to the steady state; (2) labor market institutions likely play a larger role in the adjustment process than specific human capital; (3) the short run distributional effects are small if the labor market is flexible, even in the presence of specific human capital. 相似文献

This paper constructs a model of search and bargaining across two different markets: the labor market and the housing market. Interestingly, the model highlights that housing prices and frictions in the housing market have a profound impact on labor market activity through the desire of workers to eventually purchase a home, the “American Dream.” In particular, higher housing prices adversely affect workers’ incentives in the labor market as employment can eventually lead to access to housing through the ability to purchase a home. Similarly, labor market frictions can impact housing market activity. Notably, tighter housing markets are associated with higher unemployment rates and less job creation. Consequently, our work suggests that policymakers should be very careful in implementing policies targeted towards housing – housing markets are likely to generate significant external effects to other sectors of the economy, especially the labor market. 相似文献

In this study, we investigate the allocation of talent in an economy where teachers play a critical role in developing the human capital of the workforce. To this end, we formulate a Roy model with externality in the occupational choice, as the quantity and quality of teachers are key determinants of workers’ human capital. Our analysis suggests that when individuals with greater abilities opt for teaching careers, the entire workforce benefits. However, frictions in the labor and educational goods markets may lead to a suboptimal allocation of talent and hinder economic growth and development. Our model is calibrated to the Brazilian economy, and our findings reveal a negative correlation between frictions in the teacher’s occupation and per capita output in the Brazilian states. Our results indicate that eliminating friction in the labor market could result in a 16.94% increase in Brazilian income. 相似文献

Employing an overlapping generations model of R&D‐based growth with labour market frictions, this paper examines how employment changes induced by labour market frictions influence asset bubbles and long‐run economic growth. Asset bubbles can (cannot) exist when the employment rate is high (low), which leads to higher (lower) economic growth through labour market efficiency. We also explore the steady state and transitional dynamics of bubbles, economic growth and employment. Furthermore, we show that policy or parameter changes with a negative influence on the labour market can lead to a bubble burst. 相似文献

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented. 相似文献

This paper studies firms' job creation decisions in a labour market with search frictions. A simple labour market search model is developed in which a firm can search for a second employee while producing with a first worker, and this creates the equilibrium size distribution of firms. A firm expands employment even if the instantaneous payoff to a large firm is less than that of staying small – a firm has a precautionary motive to expand its size. In addition, this motive is enhanced by a greater market tightness. Because of this effect, firms’ decisions become interdependent – a firm creates a vacancy if it expects other firms to do the same, creating strategic complementarity among firms and thereby self‐fulfilling multiple equilibria. An increase in productivity can cause a qualitative change in labour market tightness and the rate of unemployment. 相似文献

This paper considers the spillover effects from public spending, and studies optimal fiscal policies in frictional labor markets. We obtain that the optimal shares of government spending in production and consumption are the same as those in a frictionless labor market under the Hosios condition. However, as higher capital accumulation increases the cost of job creation and maintenance, the optimal tax rate of capital income is positive. In addition, when the labor market is frictional, the marginal benefit of labor is larger than the marginal utility of leisure. Thus, consumption and labor should not be taxed uniformly any more. Our calibration suggests that all of the three tax rates should be positive. Moreover, in the situation in which the Hosios condition does not hold, the shares of public productive spending and public consumption both increase when the worker’s bargaining power is greater than the elasticity of search in the matching function. 相似文献

We examine the policy implications of relaxing constraints on the educational choice of individuals for economic development. Distinguishing human capital accumulation through schooling and through learning‐by‐doing and knowledge spillovers, we show that in the earlier stages of development, mitigating and eventually eliminating constraints on school education would be necessary for even further economic development. Expanded school education increases the income of individuals and encourages physical capital accumulation, which enlarges productive knowledge through implementation and operations. The increased labor productivity thus boosts economic growth. In the process, the fertility rate will decline because of the increased education cost per child. 相似文献

Abstract. We develop an equilibrium model of the monetary policy transmission mechanism that highlights information frictions in the market for money and search frictions in the labour market. The information friction increases the persistence in the response of interest rates following monetary policy regime shifts. This occurs because agents have incomplete information about the nature of the shifts and optimally update their inflation forecasts using an 'adaptive' expectations rule. The search friction transmits the interest rate movements to the labour market by affecting job creation activities; together, the two frictions imply that unemployment reacts very gradually to monetary policy shocks.

This article provides a model of labor market equilibrium with search and within‐firm strategic bargaining. We yield explicit closed form solutions with heterogeneous labor inputs and capital. The solution exhibits overemployment. We show that higher relative bargaining power for some groups of workers may lead to overemployment relative to other groups, with such other groups being underemployed instead if they have a lower relative bargaining power. Similarly, the hold‐up problem between capitalists and employees does not necessarily lead to underinvestment in physical capital. 相似文献

We extend a second‐generation Schumpeterian growth model to incorporate human capital accumulation to clarify the general equilibrium effects of subsidy policies on human capital accumulation and R&D activities in a unified framework. Despite the conventional argument that subsidies always stimulate these growth‐promoting activities, we find that subsidies asymmetrically affect human capital accumulation and R&D activities. Our theoretical results suggest that research using standard models of human capital might find false negative relationships between education subsidies and economic growth. 相似文献

Starting a firm with expansive potential is an option for educated and high‐skilled workers. If there are labor market frictions, this additional option can be seen as reducing the chances of ending up in a low‐wage job and hence as increasing the incentives for education. In a matching model, we show that reducing the start‐up costs for new firms results in higher take‐up rates of education. It also gives rise—through a thick‐market externality—to higher rates of job creation for high‐skilled labor as well as average match productivity. We provide empirical evidence to support our argument. 相似文献

We develop a R&D‐based growth model with endogenous accumulation of human capital. We investigate the idea that education is a good entering in the preferences of individuals. We seek to analyse how the decisions of individuals to invest in human capital can be altered by changes in economic policies and how they can be reflected on the level of growth in the long run. We show that policy changes affect growth through their effect on the decision of individuals to invest in human capital. The effects obtained depend whether individuals enjoy to acquire education or if they consider it as a ‘bad’. In the absence of any policy intervention, the level of growth can be excessive or insufficient compared with the optimum. 相似文献

This paper analyzes the effects of consumption and leisure externalities on growth and welfare in a two‐sector endogenous growth model with human capital accumulation. Both types of externalities are shown to affect the long‐run equilibrium and optimal growth rates in a rather different way. The relationship between the steady state of the market and the centrally planned economy is also analyzed. The optimal growth path can be decentralized by resorting to consumption or labor income taxation, whereas capital income should be untaxed. Numerical simulations suggest that growth and welfare effects of mild consumption and leisure externalities may be quantitatively important. 相似文献

A labor market model is developed in which the formal sector is characterized by search frictions whereas the informal sector is competitive. We show that there exists a unique steady-state equilibrium in this dual economy. We then consider different policies financed by a tax on firms' profits. We find that reducing the unemployment benefit or the firms' entry cost in the formal sector induces higher job creation and formal employment, reduces the size of the informal sector but has an ambiguous effect on wages. We also find that an employment/wage subsidy policy and a hiring subsidy policy have different implications. In particular, the former increases the size of the informal sector while the latter decreases it. 相似文献
