Demographic trends and international capital flows in an integrated world

This paper examines the impact of projected demographic trends on international capital flows. The analysis builds upon a ten-region overlapping generations' model of the world economy where capital is mobile across regions. Results show that, over the first half of the century, emerging regions will finance the demand of capital coming from the developed world where population aging is relatively advanced. In particular, the findings suggest that in the coming decades China will be the world's main creditor region. However, in the second half of the century, India will take over this leading position because of the predicted decline in the Chinese labor force. An additional analysis demonstrates that the economic consequences of demographic changes depend on the degree of capital market integration between regions.     

Profit rate dynamics, income distribution, structural and technical change in Denmark, Finland and Italy

Under less restrictive assumptions than in previous contributions, this paper highlights various patterns of profit rate dynamics that are common to the countries under scrutiny. Without a substantial re-distribution of income in favour of profits, the profit rate declines. When labour productivity is weak the profits/wages ratio declines leading to a decline in the profit rate, also due to capital deepening. Developments in the capital-labour ratio tend to increase the organic composition of capital while those in the ratio between the capital price deflator and the average wage tend to decrease it. Falls in the profit rate took place in countries with a weak technological change with episodes of Marxian bias. Employment shifted from low to high capital intensity sectors, from low to high organic composition industries and from low to high productivity sectors. Rising strength of labour and realization failures tend to have a greater role than rising organic composition in cyclical profit rate dynamics. Over the cycle, the first mechanism is also the first one to show up, while the others tend to follow it. Theoretical and policy implications are offered.     

Risky human capital and deferred capital income taxation

We study the structure of optimal wedges and capital taxes in a dynamic Mirrlees economy with endogenous distribution of skills. Human capital is a private, stochastic state variable that drives the skill process of each individual. Building on the findings of the labor literature, we construct a tractable life-cycle model of human capital evolution with risky investment and stochastic depreciation. In this setting, we demonstrate the optimality of (a) a human capital premium, i.e., an excess return on human capital relative to physical capital, (b) a large intertemporal wedge early in the life-cycle, and (c) a non-zero intratemporal wedge even at the top of the skill distribution at all dates except the last date in the life-cycle. The main implication for the structure of optimal linear capital taxes is the necessity of deferred taxation of physical capital. The average marginal tax rate on physical capital held in every period is zero in present value. However, expected capital tax payments do not equal zero in every period. Necessarily, agents face negative expected capital tax payments early in the life-cycle and positive expected capital tax payments late in the life-cycle.     

Demographic structure and capital accumulation

This paper develops an overlapping-generations (OLG) model to analyze the consequences of demographic structure changes induced by an exogenous shift in the birth rate. We first show that a finite growth rate of the population that maximizes long-run capital per capita exists. Then, we examine the theoretical properties of this growth rate by showing that: (i) it corresponds to the demographic structure such that the average ages of capital holders and workers are equal; (ii) it is associated to an efficient steady state; (iii) it increases with compulsory transfers from younger to older generations. Finally, we explain why standard OLG models do not exhibit such a growth rate.     

The welfare costs of union wage compression

This paper calculates the quantitative significance of the welfare costs of union wage compression. This is done in a dynamic general equilibrium model with overlapping generations where agents choose both schooling (human capital) and assets (physical capital). The labor market in this model is characterized as a right-to-manage contract, which allows unions to compress wage differentials between high- and low-skilled workers, by implementing a binding minimum wage. This paper shows that when labor markets are competitive even low levels of wage compression lead to large welfare losses, since wage compression creates costly unemployment among low-skilled workers. The effect of wage compression on the supply of skilled labor, however, is rather small, since the disincentive effect of a lower, high-skilled wage is, to a large extent, offset by a lower opportunity cost of schooling due to higher unemployment.     

Competition, human capital and income inequality with limited commitment

We develop a dynamic model with two-sided limited commitment to study how barriers to competition, such as restrictions to business start-up and non-competitive covenants, affect the incentive to accumulate human capital. When contracts are not enforceable, high barriers lower the outside value of ‘skilled workers’ and reduce the incentive to accumulate human capital. In contrast, low barriers can result in over-accumulation of human capital. This can be socially optimal if there are positive spillovers. A calibration exercise shows that this mechanism can account for a sizable portion of cross-country income inequality.     

Competition and the capital-labor conflict

This paper analyzes the distributional effects of changes in the intensity of product market competition. The focus is on the interaction between imperfect competition in product markets and bargaining in the labor market. The main result is that, while a uniform intensification of product market competition increases employment, it may cause real wages to fall, in the short run as well as in the long run. This is especially likely if labor market regulations are favorable to workers. Therefore, product market and labor market regulations tend to reinforce each other politically, and compensatory fiscal transfers may be needed in order to enact employment-enhancing deregulation policies.     

Search efficiency,wage dynamics and welfare

Advances in information technology have improved the job-search process in the labor market. We analyze the effects of this improvement by constructing a search-and-matching model with two sectors: a risky sector with firm-specific productivity shocks and a risk-free sector. The risky sector is characterized by a low level of commitment between employers and workers – either party can end the employment relationship. We show that a better job-search process generates more job matches in the risky sector, and this benefits workers by improving their outside options. The effect on employers is subtle: while it is easier to fill vacancies, workers become more expensive. At the same time, the ease of finding new workers makes it harder for employers to keep their wage promises to workers and increases wage volatility. Our paper contributes to the literature by offering a novel explanation for the observed rise in wage volatility.     

Uncertainty and the specificity of human capital

This paper studies the choice between general and specific human capital. A trade-off arises because general human capital, while less productive, can easily be reallocated across firms. Accordingly, the fraction of individuals with specific human capital depends on the amount of uncertainty in the economy. Our model implies that while economies with more specific human capital tend to be more productive, they also tend to be more vulnerable to turbulence. As such, our theory sheds some light on the experience of Japan, where human capital is notoriously specific: while Japan benefited from this predominately specific labor force in tranquil times, this specificity may also have been at the heart of its prolonged stagnation.     

Globalization,welfare, and the attitudes toward higher education

In this paper we study how the attitudes toward higher education may affect labor market outcomes in the context of globalization. In particular, we show that different educational attitudes are responsible for differences in the wage differential among countries. Using a matching model with two types of workers and firms, we find that there is a trade-off between the wage differential and the workers’ welfare, namely, that an economy that is less willing to educate itself will display a lower wage differential but will lose in terms of welfare. Moreover, from a policy perspective, we show that the negative effects on welfare due to this disinclination to study can be offset by increased labor market flexibility. All things considered, policy makers ought to keep in mind that both a positive attitude toward higher education and labor market flexibility, can lead to improved overall performance in this increasingly globalized world.     

Do Migrants get Good Jobs in Australia? The Role of Ethnic Networks in Job Search*

We study the role of ethnic networks in migrants’ job search and the quality of jobs they find in the first years of settlement. We find that there are initial downward movements along the occupational ladder, followed by improvements. As a result of restrictions in welfare eligibility since 1997, we study whether this increases the probability that new migrants accept ‘bad jobs’ quickly and then move onto better jobs over time. Holding employability constant, our results support this view. However, accounting for their higher employability, new migrants seem to fare better up to 1.5 years after settlement.     

Global labour markets,return, and onward migration

Abstract. There is increasing evidence that international migration is characterized by frequent return and onward migration. This has important consequences for the contribution of immigrants to the economy of the host country. Lack of longitudinal data has prevented much analysis of how frequently international migration involves a sequence of location decisions or how long the typical migrant stays in a host country. A newly available longitudinal data set covering all immigrants to Canada since 1980 provides the opportunity to address these issues. The results show that a large fraction of male immigrants who are of working age, especially among skilled workers and entrepreneurs, are highly internationally mobile.     

Do Migrants Get Good Jobs? New Migrant Settlement in Australia*

The paper uses two cohorts of the longitudinal survey of immigrants to Australia data to study how changes in social security legislation in 1997 affected the quality of jobs held by new migrants. We use bivariate probit models to estimate the probabilities of holding a ‘good job’ in terms of the usual human capital and demographic variables (including visa category). Our results suggest that the policy change had a positive impact on the probability to find a job, but a negative impact to hold a good job.     

Unequal opportunities and human capital formation

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and aggregate efficiency in human capital formation. Using numerical solutions we study how the endogenous variables of the model respond to two different interventions in the distribution of opportunities: a mean-preserving spread and a change in the support. The results suggest that a higher degree of inequality of opportunities is associated with lower average level of human capital, a lower fraction of individuals investing in human capital, higher inequality in the distribution of human capital, and higher wage inequality. In particular, the model does not predict a trade-off between aggregate efficiency in human capital formation (as measured by the average level of human capital in the economy) and equality of opportunity.     

A microfoundation for increasing returns in human capital accumulation and the under-participation trap

This paper considers educational investment, wages and hours of market work in an imperfectly competitive labour market with heterogeneous workers and home production. It investigates the degree to which there might be both underemployment in the labour market and underinvestment in education. A central insight is that the ex post participation decision of workers endogeneously generates increasing marginal returns to education. Although equilibrium implies underinvestment in education, optimal policy is not to subsidise education. Instead it is to subsidise labour market participation which we argue might be efficiently targeted as state-provided childcare support.     

Population ageing,time allocation and human capital: A general equilibrium analysis for Canada

This study explores the long-term impact of population ageing on labour supply and human capital investment in Canada, as well as the induced effects on productive capacity. The analysis is conducted with a dynamic computable overlapping generations model where in the spirit of Becker [Becker, Gary (1965), A theory of the allocation of time, The Economic Journal, Vol. 75, pp. 493–517.] and Heckman [Heckman, James (1976), A life-cycle model of earnings, learning and consumption, The Quarterly Journal of Economics, Vol. 84, pp. 511–544], leisure has a quality-time feature and labour supply and human capital investment decisions are endogenous. The role of human capital in the growth process is based on the framework used by Mankiw et al. [Mankiw, N. Gregory, Romer, David and Weil, David N. (1992), A contribution to the empirics of economic growth, Quarterly Journal of Economics, Vol. 107, no. 2, pp. 407–437]. The paper indicates that population ageing creates more opportunities for young individuals to invest in human capital and supply more skilled labour at middle age. Consequently, the reduction in labour supply of young adults initially lowers productive capacity and exacerbates the economic costs of population ageing. However, current and future middle-age cohorts are more skilled and work more, which eventually raises productive capacity and significantly lowers the cost of population ageing. Finally, these results suggest that the recent increase in the participation rate of older workers might be the beginning of a new trend that will amplify over the next decades.     

Unemployment dynamics with international capital mobility

We study the response of domestic unemployment rates to shocks in total factor productivity for economies with high capital mobility and low labour mobility. We show that high capital mobility amplifies the impact on the domestic unemployment rate of domestic fluctuations in total factor productivity, shortens the lag of the response to shocks and raises the variability of unemployment. But average unemployment is unaffected. Capital flows increase the riskiness of labour income and reduce the riskiness of capital income but do not reduce mean welfare.     

Learning the master's trade: Apprenticeship and human capital in Ghana

This paper explores the institution of apprenticeship in Ghana. A model is presented where apprenticeship training is idiosyncratic, increasing an individual's productivity in the current firm, but not in any other firm. Still, individuals are willing to fund apprenticeships as they can reap the returns to the specific training of apprenticeship if they manage to acquire the capital required to start their own firms, and replicate the technology and business practice of the apprenticeship firm. Predictions of the model for the productivity and remuneration of different workers are developed and tested using both a linked employer–employee survey of manufacturing firms and a national household survey.     

Progressive taxation and human capital as determinants of inflation persistence

In this study, we introduce progressive taxation and human capital differences across productive sectors into a typical monetary policy game. The objective of this work is to reveal the potential short-run effects of these two typical features of economic growth on inflation dynamics. In our framework, such features act as frictions of labor mobility across sectors. We show that an increased progressivity of taxation lowers the diffusion of shocks, and in turn increases inflation persistence. Moreover, the dispersion of human capital across sectors acts as a barrier to labor mobility and thereby increasing inflation inertia through the same channel. We also empirically verify these findings by employing panel data analysis in a sample of 28 OECD countries.     

Using Copulas to Model Switching Regimes with an Application to Child Labour*

The copula approach to econometric modelling involves the specification of the separate components of the joint distribution of the random variables of interest: models built for each margin are bound together using a copula function. In this paper, the copula approach is used to construct models for switching regimes. The construct is illustrated by fitting a wage earnings model for child workers in the early 1900s, with regimes governed according to literacy. The results improve on earlier modelling efforts by Poirier and Tobias (2003), finding that a child worker may on average expect a reduction in earnings from being literate.
