We develop a dynamic multiregion model, where a household's choice of housing location depends on its current wealth and its current type, and involves both consumption and investment considerations. The relative strength of the consumption motive and the investment motive determines the equilibrium pattern of residential sorting. A strong investment (consumption) motive implies sorting according to household type (wealth). The model predicts that large house‐price fluctuations are associated with a low degree of sorting by type. This prediction is consistent with evidence from US metropolitan areas when income, education, and age are used as proxies for household type.  相似文献

This paper presents a Kaleckian growth model in which (i) the rate of capacity utilization, the profit share, and the rate of employment are adjusted in the medium run, and (ii) the normal rate of capacity utilization and the expected rate of capital accumulation are adjusted in the long run. The long-run equilibrium is a continuum of equilibria and is characterized by hysteresis in that the long-run position of the economy depends on where it starts. An increase in the bargaining power of workers lowers the rate of unemployment in both the medium-run and the long-run equilibrium.  相似文献

Obesity rates have been rising over the past decade. As more people become obese, the social stigma of obesity may be reduced. Marriage has typically been used as a positive signal to employers. If obese individuals possess other characteristics that are valued in the labour market they may no longer face a wage penalty for their physical appearance. This paper investigates the relationship between marital status, body mass index (BMI), and wages by estimating a double selection model that controls for selection into the labour and marriage markets using waves 14 and 16 (2004 and 2006) of the British Household Panel Survey. Results suggest that unobserved characteristics related to marriage and labour market participation are causing an upward bias on the BMI coefficients. The BMI coefficient is positive and significant for married men only in the double selection model. The findings provide evidence that unobserved characteristics related to success in the marriage and labour market may influence the relationship between BMI and wages.  相似文献

A politicoeconomic model dealing with the interaction of private innovation and public regulation is presented. Causes and effects of this interdependence are investigated with special regard to the externalities which accompany innovations and make them into a partly public good. Our main hypothesis is that the collective character of inventive activity gives rise to synergetic effects. This hypothesis is supported by a microfoundation based on a nonlinear Markov process. Furthermore, the consequences of such synergetic innovation processes are examined: persistent disequilibrium, multiple equilibria, lock-in, path dependence, and chaos. Finally, some policy implications are derived concerning the effects of ageneral public promotion of innovations and of aselective industrial policy.  相似文献

Poverty, Growth, and Redistribution: a Study of Iran   总被引:1,自引:0,他引:1  
The paper examines changes in the extent of poverty in Iran in the period 1983 to 1993. More specifically, it investigates the contributions of growth and redistribution factors to changes in poverty over this period of ten years. The analysis is based on household‐level data relating to three Household Income and Expenditures Surveys of 1983, 1988, and 1993. The study reveals that the extent of poverty in the rural sector declined slightly, whereas in the urban sector it increased significantly. Decomposition of changes in poverty into growth and redistribution components indicates that in each sector the redistribution component was positive, implying that the deterioration of income inequality contributed to the worsening of poverty. The growth component, however, affected the two sectors differently: it contributed to a reduction in poverty in rural areas and an increase in urban areas.  相似文献

This paper analyzes the relationship between market shares and welfare under the assumption of Cournot-oligopolistic interdependence in production. The model is general enough to deal with multiple countries, oligopolists with different levels of marginal costs within each country, and any distribution of world demand across countries. It is found that the elimination of a minor firm harms the country if the country's total production is very little. However, such a policy always benefits the country if it exports the commodity. The welfare effect of production subsidies and the case of foreign ownership of firms are also discussed.  相似文献

Much of the lending in modern economies is secured by some form of collateral: residential and commercial mortgages and corporate bonds are familiar examples. This paper builds an extension of general equilibrium theory that incorporates durable goods, collateralized securities, and the possibility of default to argue that the reliance on collateral to secure loans and the particular collateral requirements chosen by the social planner or by the market have a profound impact on prices, allocations, market structure, and the efficiency of market outcomes. These findings provide insights into housing and mortgage markets, including the subprime mortgage market.  相似文献

In this article, we analyse the trade–growth nexus for Slovakia. This country represents a critical case for such research because it is one of the most open economies in the world; by several measures it is the most open economy in the EU, with the most Eurocentric trade, and has maintained one of the best growth performances within the EU over a sustained period of time. In contrast to most contributions to the trade–growth literature, we analyse all six possible causal relationships between Slovakia’s exports, imports and growth, using the technique developed by Toda and Yamamoto (1995), on quarterly data from 1997Q1 to 2014Q4. We find evidence supporting both the export-led-growth hypothesis and the import-led-growth hypothesis. None of the other four relationships was found to be significant.  相似文献

The paper analyses the determinants of self-reported work effort using a 1988 survery of Australian employees. While controlling for the endogeneity of the firm's choice of incentives and pay, it is found that direct incentive schemes have predicted effects, and the efficiency wage hypothesis is supported: pay and work effort are positively correlated. Two efficiency wage models are tested: Akerlof's gift exchange model, and work discipline arguments regarding monitoring difficulties and threats of dismissal. The latter argument is broadly consistent with the data.  相似文献

Population,food, and knowledge: a simple unified growth theory   总被引:6,自引:3,他引:3  
This paper provides a unified growth theory, i.e. a model that explains the very long-run economic and demographic development path of industrialized economies, stretching from the pre-industrial era to the present-day and beyond. Making strict use of Malthus’ (An essay on the principle of population. London, printed for J. Johnson, 1798) so-called preventive check hypothesis—that fertility rates vary inversely with the price of food—the current study offers a new and straightforward explanation for the demographic transition and the break with the Malthusian era. Employing a two-sector framework with agriculture and industry, we demonstrate how fertility responds differently to productivity and income growth, depending on whether it emerges in agriculture or industry. Agricultural productivity and income growth makes food goods, and therefore children, relatively less expensive. Industrial productivity and income growth, on the other hand, makes food goods, and therefore children, relatively more expensive. The present framework lends support to existing unified growth theories and is well in tune with historical evidence about structural transformation.   相似文献

It is the purpose of this paper to elaborate on the argumentthat formalism is non-neutral; analyses which today would bedescribed as informal turn into something quite different whenformalised. The reasons for non-neutrality refer to the choiceof assumptions or axioms, the choice of method, the type oflogic employed and closure. Focusing on the last three of these,the paper addresses the question of how to move from resultsobtained with formal methods under conditions of closure tothe reality one is attempting to model. We explore the needfor provisional closure to analyse open systems and for a rangeof methods to complement formal modelling in the attempt tounderstand the complex reality of an economic system.  相似文献

ABSTRACT

The association between foreign aid and growth has been controversial for decades and the evidence is quite mixed with results sensitive to data samples and modelling approaches. We reassess the relationship between aid, policy and growth implementing a novel semiparametric estimation method that allows for nonlinearities and controls for endogeneity. The results show that the aid-policy-growth relationship is complex. Aid inflows do not seem growth-enhancing, except at very high levels (above 7% of Aid/GDP), whereas the effect may arrive with a lag at lower levels. Policy improvements are positively correlated with growth at high policy levels (above the median value) but better policies do not increase aid effectiveness.  相似文献
