This article is a first step towards understanding the relationship between credit market imperfections and inequality of opportunity in skill formation. The main goal is to investigate the effects of the credit constraint on the optimal human capital decision, in terms of degree of schooling, taking into account the household preferences for education. Our starting point is a theoretical model of human capital investment decision with credit constraint. Following a previous model in the literature, we propose a reduced-form approach that estimates the relation between education decision and initial wealth in Brazil. Our empirical analysis is conducted using data from a Brazilian Household Budget Survey (Pesquisa de Orçamentos Familiares), for years 2002–2003 and 2008–2009. Our results point out that education decision is in fact credit constrained. The empirical results show a strong and highly significant effect of wealth on educational level of children, teenagers and adults, even controlling by education expenditures. But we find no evidence of credit constraint on high level education decision, like undergraduate and graduate levels.  相似文献

Vintage capital and the dynamics of the AK model   总被引:2,自引:0,他引:2  
This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vintage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionally influence the intercept of the balanced growth path. These features, which are in sharp contrast to those from the standard AK model, can contribute to explaining the short-run deviations observed between investment and growth rates time series. To characterize the optimal solutions of the model we develop analytical and numerical methods that should be of interest for the general resolution of endogenous growth models with vintage capital.  相似文献

In this paper, we propose a temporal disaggregation model with regime switches to disaggregate U.S. quarterly GDP into monthly figures. Alternative to the existing literature, our model is able to capture the nonlinear behaviors of both aggregated and disaggregated output series as well as the asymmetric nature of business cycle phases. To demonstrate the applicability of the proposed model, we apply the model with a Markov trend component to U.S. quarterly real GDP. The results suggest that the combination of a temporal disaggregation model with Markov switches leads to a successful representation of the data relative to the existing literature. Also, the inferred probabilities of unobserved states are clearly in close agreement with the NBER reference cycle on a monthly basis, which highlights the importance of nonlinearities in business cycle.  相似文献

We estimate the impact of exchange rate volatility on firms' investment decisions in a developing country setting. Employing plant-level panel data from the Colombian Manufacturing Census, we estimate a dynamic investment equation using the system-GMM estimator developed by Arellano and Bover (1995) and Blundell and Bond (1998). We find a robust negative impact of exchange rate volatility, constructed either using a GARCH model or a simple standard deviation measure, on plant investment. Consistent with theory, we also document that the negative effect is mitigated for establishments with higher mark-up or exports, and exacerbated for lower mark-up plants with larger volume of imported intermediates.  相似文献

Abstract This paper presents an empirical analysis of outsourcing behaviour by French manufacturing industries. It focuses on the effects of market thickness, sunk costs, and the productivity of firms on the outsourcing decision. I estimate a dynamic probit model where outsourcing decision is linked to past outsourcing behaviour. The results show that outsourcing is a persistent strategy adopted by large firms and suggest the presence of significant sunk costs associated with outsourcing. The results also show that market thickness reduces search costs and enhances the establishment of outsourcing relationships.  相似文献

We study how producers of capital goods set shipments in response to fluctuations in new orders. We find that shipments respond more to orders when new orders fall below a certain level relative to shipments, usually after orders plunge in recessions. This cyclical change in producers’ behavior accounts for a considerable portion of the downturn in equipment investment in the 2001 and 2008–9 recessions. A simple model of production to order suggests that heightened persistence in new orders growth may explain the greater responsiveness of shipments, as may increases in the producers’ target delivery lag.  相似文献

This paper discusses the impact of foreign savings on aggregate spending categories in Turkey. Using the vector autoregressive (VAR) models the major finding is that foreign savings has an increasing effect on consumption. The increase of investment arises from the accelerator effect of consumption, which results in an upward trend in investment in non-tradable sectors. Concluding that the policy of relying on foreign savings, to obtain long-term increases in tradable sector investment and competitiveness is ill-judged.  相似文献

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimal competitive equilibrium allocations. Furthermore, we provide tests of Pareto optimality/suboptimality based on (risky) rates of return only.  相似文献

In this paper we develop the dynamic CGE model, ifoMod, which is designed to analyse the impact of fundamental tax reforms and in particular capital income tax reforms for Germany. The model is in line with neoclassical growth theory and features all important behavioural interactions between the four major building blocks of an economy including the firm and household sector, the government and the rest of the world. We consider firms of different legal forms which all face an intertemporal investment problem, a financing problem w.r.t. the optimal choice of debt and equity financing as well as a factor input problem when deciding on the optimal amount of different skill types of labour employed. We show the impact of different types of taxes on the behavioural margins of firms and households. The conducted simulation shows the impact of the latest German corporate tax reform of 2008 on the German macroeconomic variables such as investments, GDP, consumption and household's welfare.  相似文献

International transmission of the business cycle in a multi-sector model   总被引:2,自引:0,他引:2  
Standard multi-country models do not replicate important features of the international transmission of business cycles, predicting cross-country correlations of output and consumption which are, respectively, too low and too high. In this paper we modify the supply side of a two-country model by adding multiple sectors and trade in intermediate goods. The model generates a higher cross-country correlation of output than standard one-sector models. It also predicts cross-country correlations of employment and investment that are closer to the data. We analyze the relative impact of multiple sectors, trade in intermediate goods, imperfect substitution between domestic and foreign goods, home preference, capital adjustment costs, and capital depreciation in order to pinpoint the features which move the model's predictions closer to the data.  相似文献

Grandmont (1985) found that the parameter space of the most classical dynamic general-equilibrium macroeconomic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic stability at one extreme to chaos at the other extreme, and with all forms of multiperiodic dynamics between.  相似文献

Estimation of the business cycle: A modified Hodrick-Prescott filter   总被引:1,自引:0,他引:1  
Hodrick-Prescott (HP) filtering of (most often, seasonally adjusted) quarterly series is analysed. Some of the criticism to the filter are adressed. It is seen that, while filtering strongly affects autocorrelations, it has little effect on crosscorrelations. It is argued that the criticism that HP filtering induces a spurious cycle in the series is unwarranted. The filter, however, presents two serious drawbacks: First, poor performance at the end periods, due to the size of the revisions in preliminary estimators, and, second, the amount of noise in the cyclical signal, which seriously disturbs its interpretation. We show how the addition of two model-based features (in particular, applying the filter to the series extended with proper ARIMA forecasts and backcasts, and using as input to the filter the trend-cycle component instead of the seasonally adjusted series) can considerably improve the filter performance. Throughout the discussion, we use a computationally and analytically convenient alternative derivation of the HP filter, and illustrate the results with an example consisting of 4 Spanish economic indicators.  相似文献

We develop a new structural Vector Autoregressive (SVAR) model for analysis with mixed-frequency data. The MIDAS-SVAR model allows to identify structural dynamic links exploiting the information contained in variables sampled at different frequencies. It also provides a general framework to test homogeneous frequency-based representations versus mixed-frequency data models. A set of Monte Carlo experiments suggests that the test performs well both in terms of size and power. The MIDAS-SVAR is then used to study how monetary policy and financial uncertainty impact on the dynamics of gross capital inflows to the US. While no relation is found when using standard quarterly data, mixed frequency analysis exploiting the variability present in the series within the quarter shows that the effect of an interest rate shock is greater the longer the time lag between the month of the shock and the end of the quarter.  相似文献

In this paper, we first study the relationship between the financial cycle and the business cycle in the time and frequency domain. Then we also explore the interactions and dynamic mechanisms of the financial cycle, the business cycle, real interest rate and exchange rate by the VAR model. The empirical results show that the financial cycle is closely related to the business cycle, especially at medium-term frequencies (8–30 years), the business cycle leads the financial cycle with a high positive correlation. However, the relationship between them is not significant during the Great Moderation at business-cycle (2–4 years). In addition, the financial cycle not only becomes a main driver of real interest rate, the financial cycle and the business cycle, but also serves as an important source of the business cycle fluctuations. In general, our results lay some theoretical foundation for the policy practice of financial and economic stability.  相似文献

A number of studies have appeared in the area of cross-country consumption comparisons, where a common system of demand equations is used to model the consumption patterns of all countries. Under this approach, tastes are taken to be the same internationally. Such an assumption of identical tastes was forcibly advocated by the dual Nobel laureates, Stigler and Becker, who argued that tastes neither change capriciously nor differ importantly between people. In this paper, we use the system-wide approach to demand analysis to analyse the alcohol consumption patterns of drinkers from 10 high-income industrialised countries and verify Stigler and Becker’s (Rev Econ Statist 59:113–118, 1977) hypothesis by testing whether pooling the data across countries is acceptable. We also present the implied demand elasticities for beer, wine and spirits for the 10 countries and discuss the use of these elasticities in policy-related applications.  相似文献

This paper examines the effect of expanding public health insurance in South Korea on medical expenditures and aggregate saving using an overlapping generations model with endogenous health risk. South Korea had a substantial underinsured population, which is aging rapidly. Higher public health insurance benefits reduce individual medical expenditure and health risks but lead to a modest decline in individual and aggregate saving. Even after the expansion, the medical care coverage remains incomplete, and the elderly face a substantial risk of out-of-pocket medical expenditures.  相似文献

In this paper, the long-run incidence of a tax on pure rent is analyzed in an OLG two-sector small open economy, in which one sector produces a capital good and one sector a consumer good. Contrary to what is obtained in a one-sector closed economy, a land rent tax does not necessarily foster nonhumam wealth accumulation and capital formation. The accommodating scheme for the government budget plays a crucial role for the effects of pure rent taxation. A rent tax stimulates nonhuman wealth if distortionary taxes on wealth or on income from nonland inputs are alleviated. The mechanism spurring capital formation is brought into action, instead, only when the rent tax is matched by a fall in capital taxation or, if the capital sector is capital intensive, by an increase in government spending on the capital good.  相似文献

Now that a number of central banks are faced with short-term nominal interest rates close to or at the zero lower bound, there is a renewed interest in the long-running debate about whether or not changes in the stock of money have direct effects. In particular, do changes in money have additional effects on aggregate demand outside of those induced by changes in short-term nominal interest rates? This article revisits and reinterprets the empirical evidence based on single equation regressions which is quite mixed, with some results supporting and other results denying the existence of direct effects. We use a structural model with no direct effects of money to show that the finding of positive and statistically significant coefficients on real money growth can be misleading. The model generates data that, when used to estimate analogues of the empirical regressions, produce positive and statistically significant coefficients on real money growth, similar to those often found when using actual data. The problem is that single equation regressions leave out a set of variables, which in turn, give rise to an omitted variables bias in the estimated coefficients on real money growth. Hence, they are an unreliable guide to calibrate monetary policies, in general, including at the zero lower bound.  相似文献

The impact of natural disasters on the Australian equity market is examined. The data set employed consists of daily price and accumulation returns over the period 31 December 1982–1 January 2002 for the All Ordinaries Index (AOI) and a record of 42 severe storms, floods, cyclones, earthquakes and bushfires (wildfires) during this period with an insured loss in excess of A$5 mil. and/or total loss in excess of A$100 mil. Autoregressive moving average (ARMA) models are used to model the returns and the inclusion of news arrival, in the form of the natural disasters, is specified using intervention analysis. The results indicate that bushfires, cyclones and earthquakes have a major effect on market returns, unlike severe storms and floods. The net effects can be positive and/or negative with most effects being felt on the day of the event and with some adjustment in the days that follow.  相似文献
