Demographic change,human capital accumulation and R&D‐based growth

Employing an overlapping generations model of R&D‐based growth with endogenous fertility and education decisions, we examine how demographic changes induced by an increase in life expectancy influence the long‐run growth rate of the economy. We demonstrate that life expectancy, when relatively low (high), positively (negatively) affects economic growth. This paper also compares the growth implications of child education subsidy policies (i.e., policies for enhancing basic education) and child rearing subsidy policies (i.e., pro‐natal policies) and demonstrate that while the child education subsidies consistently foster economic growth, child rearing subsidies may negatively affect economic growth.     

The effect of education subsidies on regional economic growth and disparities in China

This paper examines the impact of education subsidies on regional economic growth and the disparities between two Chinese regions, Jiangsu and Liaoning, by simulating their economies in a six-period overlapping generations model in which individuals decide their length of education. This study estimates the long-run growth rates, that is, the steady growth paths of the regional economies based on current education subsidies, and explores their effect on human capital accumulation, namely in terms of economic growth while considering the increase in education subsidies. Because greater government subsidies in education induce individuals to invest in human capital, both regions achieve higher economic growth. Moreover, because of the large differences in productivity between the regions, the growth gap widens with evenly raised education subsidy rates.     

The interactions among foreign direct investment,economic growth,degree of openness and unemployment in Taiwan

The vector autoregression method of variance decomposition and impulse response function analysis are applied to analyse various relationships among foreign direct investment (FDI), economic growth, unemployment and degree of openness in Taiwan. The analysis results show that these five variables have a long-run equilibrium relationship; however, unemployment rate and FDI outflow have weak exogeneity. We also found that there exist three unidirectional causalities from FDI outflow to FDI inflow, from economic growth to degree of openness, and from economic growth to unemployment in short-run. Furthermore, the shocks of economic growth and degree of openness have positive effects on FDI inflow. On the contrary, the shocks in economic growth and FDI inflow have negative effects on unemployment rate.     

On economic growth and minimum wages

We offer an analysis of the existence of a positive relationship between minimum wages and economic growth in a simple one-sector overlapping generations economy à la Romer (J Polit Econ 94:1002–1037, 1986), in the case of both homogeneous and heterogeneous labour and without considering any growth-sustaining externalities which the minimum wage can generate. Assuming also the existence of unemployment benefits financed with balanced-budget consumption taxes not conditional upon age, we show that the minimum wage can promote economic growth and welfare despite the occurrence of unemployment. There may also exist a growth- and welfare-maximising minimum wage.     

Education,Innovation and Long‐Run Growth

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.     

Occupational choice and entrepreneurship: effects of R&D subsidies on economic growth

Most R&D-based growth models fail to explicitly account for the role of entrepreneurs in economic growth. By contrast, this study accounts for this factor and constructs an overlapping-generations model that includes entrepreneurial innovation and the occupational choice of becoming an entrepreneur or a worker. For the role of entrepreneurs, even a policy intended to encourage innovation can negatively affect economic growth. For the effect of such policies, I focus on the role of R&D subsidies. I show that while R&D subsidies promote entrepreneurs’ R&D activities, they increase workers’ wages by boosting labor demand. Thus, it is more attractive to be a worker, which reduces the number of entrepreneurs. Subsidies can have both a negative and positive effect on growth, which results in an inverted U-shaped relationship between R&D subsidies and growth. In addition, a growth-maximizing R&D subsidy rate exists, although this rate is too high to maximize the welfare level of any one generation. When individuals are heterogeneous in their abilities, R&D subsidies reduce intra-generational inequalities.     

Training policies and economic growth in an evolutionary world

The role of training and human capital accumulation as a source of innovation and growth is studied within an evolutionary microsimulation model. Firms within the model learn about technology through radical/incremental innovation and imitation. General human capital increases the probability of innovation whereas specific human capital increases technical efficiency. Firms endogenously determine the level of investment in fixed and current assets, R&D activities, and education and training. Human capital accumulation through investment in education and training is shown to be a source of economic growth even though firms tend to under-invest in these activities because they cannot fully recoup training costs when workers quit. The paper investigates the effects of various training policies on macro-performance. The first policy is to subsidise all education and training activities. The second policy requires firms to spend a certain percentage of the wage bill on training activities. In the third case, the government subsidises training activities if the firm hires unemployed people, and pays the social security contributions for 1 year. We experiment with these policies because many European countries adopt similar policies to cure the unemployment problem and to enhance economic growth. By running 101 experiments for each policy, increasing the parameter value step by step, we are able to test the impact of training policies on macro-economic performance (manufacturing growth rates, unemployment, etc.), and to estimate policy elasticities through econometric techniques. The results suggest that some subsidy policies are effective in improving the long-run macro-performance while a minimum requirement to train set upon firms is not.     

Non-scale endogenous growth effects of subsidies for exporters

We built a general equilibrium endogenous growth model in which final goods are produced either in the relatively skilled-labour intensive exports sector or in the relatively unskilled-labour intensive domestic sector. We show that, by affecting the technological-knowledge bias, subsidies explain the simultaneous rise in the exports sector, the skill wage premium and the economic growth rate. Then, to shed light upon the causal nexus between production-related subsidies and exports, we use a Portuguese longitudinal database (1996–2003) and implement a propensity score matching approach. Empirical results seem to prove the theoretical predictions: subsidies generate the rise in the wage premium of exporters and the increase in the relative size of export sector, even if no impact of subsidies is found in the capacity of transforming domestic firms into new exporters.     

Unemployment insurance, moral hazard, and economic growth

It is important but difficult to distinguish between desirable and undesirable effects of unemployment insurance (UI) that are observationally equivalent when designing optimal UI schemes. For example, a UI-induced rise in the wage rate caused by workers taking more time to match their skills with job vacancies is desirable. However, another view of the same observation is that UI causes permanently higher involuntary unemployment by raising the reservation wage. This paper avoids this problem by regarding the trade-off between the UI replacement rates and unemployment as an intermediate relationship that matters only as far as it impacts economic growth. An empirical analysis of UI replacement rates, unemployment rates, and growth rates using annual panel data finds UI replacement rates are associated with higher unemployment. However, no significant relationship is found between UI-related unemployment and the real growth rate of gross domestic product.An earlier version of this paper was presented at the Fiftieth International Atlantic Economic Conference, October 15–18, 2000, Charleston, South Carolina.

Age effects in Okun’s law with different indicators of unemployment

We reassess the results from the literature on the relationship between the youth unemployment rate and GDP growth (Okun’s law), based on the concern that the unemployment rate is not an ideal indicator for teenagers and young adults. Using the unemployment ratio instead, we find that youth unemployment (15–24 years old) is not significantly more responsive to economic growth than prime-age (25–64) unemployment. However, compared to prime-age unemployment, teenagers’ unemployment (15–19) is relatively unresponsive, whereas young adult’s (20–24) unemployment is more strongly correlated with economic growth. These results are quite different than those obtained with the unemployment rate as the dependent variable.     

R&D-expenditure in an endogenous growth model

The aim of this paper is to analyze the role that aggregate R&D-expenditure plays in economic growth. We introduce a technology of innovation based on expenditure that generates endogenous sustainable growth in absence of any scale effect. This R&D-model permits us to study the effects of some fiscal policies. In particular, we analyze how subsidies to R&D-investment and physical capital accumulation affect the long-run growth rate. For the empirical cross-country analysis we directly derive a structural econometric model.     

Can regional policy in a federation improve economic efficiency?

In the European Union and in many federal and non-federal countries, the central government pays subsidies to poor regions. These subsidies are often seen as a redistributive measure which comes at the cost of an efficiency loss. This paper develops an economic rationale for regional policy based on economic efficiency. We consider a model of a federation consisting of a rich and a poor region. The economy is characterized by imperfect competition in goods markets and unemployment. Firms initially produce in the rich region but may relocate their production to the poor region. We show that a subsidy on investment in the poor region unambiguously increases welfare if labour markets are competitive. If there is unemployment in both regions, the case for regional subsidies is weaker.

文章构建了三部分模型,分析了知识产权保护、政府补贴对经济增长的作用,研究发现:知识产权保护对经济增长的作用是不确定的,根据本国自主创新的程度而异;政府补贴份额的增加有助于放大严格的知识产权保护对经济增长的正面效应或减缓严格的知识产权保护对经济增长的负面效应;政府补贴与经济增长休戚相关,政府补贴份额越高,越有利于经济增长;严格的知识产权保护会放大或消弭政府补贴对经济增长的正面效应;技术应用成本与经济增长呈现反向关系,技术应用成本越高,越不利于经济增长,较高的政府补贴份额会减缓技术应用成本对经济增长的负面影响;严格的知识产权保护会放大或减缓技术应用成本对经济增长的负面效应。     

Inequality,unemployment, and endogenous growth in a political economy with a minimum wage

This paper presents development of an endogenous growth model with heterogeneous households and political determination of the minimum wage. We investigate the interaction of inequality, unemployment, and economic growth. First, the arguments in this paper show that a positive correlation exists between inequality and unemployment, Second, the interaction between inequality and economic growth is shown to be a positive relation if high inequality pertains in a society. It is a negative relation if low inequality pertains.      

Unemployment, growth and taxation in industrial countries

To the layman, the upward trend in European unemployment is related to the slowdown of economic growth. We argue that the layman's view is correct. The increase in European unemployment and the slowdown in economic growth are related, because they stem from a common cause: an excessively rapid growth in the cost of labour. In Europe, labour costs have gone up for many reasons, but one is particularly easy to identify: higher taxes on labour. If wages are set by strong and decentralized trade unions, an increase in labour taxes is shifted onto higher real wages. This has two effects. First, it reduces labour demand, and thus creates unemployment. Secondly, as firms substitute capital for labour, the marginal product of capital falls; over long periods of time, this in turn diminishes the incentive to invest and to grow. The data strongly support this view. According to our estimates, the observed rise of 14 percentage points in labour tax rates between 1965 and 1995 in the EU could account for a rise in EU unemployment of roughly 4 percentage points, a reduction of the investment share of output of about 3 percentage points, and a growth slowdown of about 0.4 percentage points a year.     

Relation between growth and unemployment in a model with labor-force participation and adverse labor institutions

Based on labor search models with an exogenous labor force, existing papers have found a negative relation between long-run economic growth and unemployment. Motivated by the fact that the labor force participation has changed substantially across OECD countries, this paper revisits the long-run relation by taking account of endogenous labor-force participation. We find that, via the effects on employment, changes in labor market institutions may increase or decrease long-run economic growth. Moreover, depending upon the effects on the labor force and employment, these labor market institutions may increase or decrease unemployment rates in the long run. Thus, changes in labor market institutions lead to a non-monotone relation between long-run economic growth and unemployment that is consistent with the data.     

ROLLING REGRESSION VERSUS TIME‐VARYING COEFFICIENT MODELLING: AN EMPIRICAL INVESTIGATION OF THE OKUN'S LAW IN SOME EURO AREA COUNTRIES

During the last decade, economists have shown that the inverse relationship between economic growth and unemployment rate varies over time. Rolling regression has been the main tool used to quantify such a relationship. This methodology suffers from several well‐known problems which lead to spurious non‐linear patterns in the Okun's coefficient behaviour over time. Here, we take a penalized regression spline approach to estimate the Okun's time‐varying effects. As a result, spurious non‐linearities are suppressed and hence important time‐varying coefficient features revealed. Our empirical results show that the inverse relationship in some Euro area countries is spatially heterogeneous and time‐varying. The findings are complemented by the calculation of the rate of output growth needed for a stable unemployment rate, as proposed by Knotek.     

Regional analysis of the impact of inward foreign direct investment on economic growth in the Chinese electronic industry

This article empirically investigates the impact of inward foreign direct investment (FDI) on regional economic growth in the Chinese electronic industry (CEI). Utilizing a provincial-level panel data spanning the period 1989 to 2009, we specify and estimate an endogenous economic growth model for the CEI. Empirical results indicate that, for the coastal region, FDI inflows have been growth enhancing, while in the central and western regions the impact of FDI on economic growth is mixed, depending on the channel of capital flow. Results also indicate that exports, human capital, science and technology investment and fixed asset investment are growth enhancing, while unemployment and foreign R&D investment are growth impeding in the CEI.
