Child labor and household wealth: Theory and empirical evidence of an inverted-U

Some studies on child labor have shown that, at the level of the household, greater land wealth leads to higher child labor, thereby casting doubt on the hypothesis that child labor is caused by poverty. This paper argues that the missing ingredient may be an explicit modeling of the labor market. We develop a simple model which suggests the possibility of an inverted-U relationship between land holdings and child labor. Using a unique data set that has child labor hours it is found that, controlling for child, household and village characteristics, the turning point beyond which more land leads to a decline in child labor occurs around 4 ac of land per household.     

Collateral constraints and rental markets

We study a benchmark model with collateral constraints and heterogeneous discounting. Contrarily to a rich literature on borrowing limits, we allow for rental markets. By incorporating this missing market, we show that impatient agents choose to rent rather than to own the collateral in the neighborhood of the deterministic steady state. Consequently, impatient agents are not indebted and borrowing constraints play no role in local dynamics.     

Inflation,nominal portfolios,and wealth redistribution in Canada

Abstract This paper quantifies the redistributional effects of inflation in Canada that arise through the revaluation of nominal assets and liabilities. We find that the effects are non‐trivial even for low inflation episodes. The main winners are young, middle‐class households with mortgage debt. The government receives a windfall gain from its long‐term debt. The old, the rich or the middle‐aged, middle‐class lose, largely owing to their holdings of bonds and non‐indexed defined benefit pension assets. Finally, our Canada‐U.S. comparison reveals that the extent of redistributions can be quite different even between countries of similar economic and legal environments.     

Earnings Dynamics and Profile Heterogeneity: Estimates from Japanese Panel Data

The recent empirical work on earnings processes using US panel data finds that ignoring heterogeneity in earnings profiles among individuals leads to an upward bias in the autoregressive parameter of earnings shocks. It then argues that the existing assumptions in incomplete markets and heterogeneous‐agent models, almost all of which require highly persistent earnings shocks and no individual‐specific and group‐specific differences in earnings growth rates, may be inappropriate. This paper investigates the applicability of this US data‐based debate to other developed countries by using a panel of Japanese male earnings. The results indicate that it is possible to corroborate the recent US arguments, despite some differences in the estimates.     

Incentives and performance in the presence of wealth effects and endogenous risk

Two of the most widely tested predictions of agency theory are that there exists a negative association between an agent's pay-performance sensitivity (PPS) and the risk of output, and that PPS enhances performance. Empirical evidence has been mixed. This paper proposes a new utility function and develops a model that introduces a “wealth effect” and also allows the agent to control the (idiosyncratic) risk of output. When risk is endogenous, the paper shows that the two predictions may not hold.     

Tax treatment of owner occupied housing and wealth inequality

We construct a quantitative general equilibrium lifecycle model with housing tenure decisions to investigate the degree to which wealth inequality in the United States is affected by the preferential tax treatment of home-ownership. Favorable tax treatment of owner occupied housing in the form of home mortgage interest and property tax deductibility, and the untaxed nature of imputed rents, provides a financial incentive for home-ownership over renting as well as an incentive to “over-consume” housing since houses are not fungible. Since the favorable tax treatment of housing disproportionately creates tax savings for the upper quantiles of the income distribution, we quantify how it contributes to the heavily right skewed distribution of wealth in the United States using data from the Survey of Consumer Finances. We consider a revenue-neutral government response to the counter factual experiments of removing the current tax structure on housing. Our quantitative analysis shows that, in terms of distributional effects, removing all of the preferential tax treatments results in an aggregate increase in welfare. However, we do not find any reduction in inequality. We also find that while some re-allocation toward financial assets occurs, households primarily increase their consumption when imputed housing rents are taxed and the property tax deduction is removed. Thus housing tax policy may be effective at encouraging more overall saving through housing assets.     

Modes of foreign bank entry and effects on lending rates: Theory and evidence

Policy makers who decide to liberalize foreign bank entry frequently put limitations on the mode of entry. We study how different entry modes affect the lending rates of foreign and domestic banks. In our model, the mode of entry determines whether a foreign bank inherits a customer base. This, in turn, affects how information is distributed between foreign and domestic banks. We show that this distribution of information about incumbent customers leads to stronger competition if foreign entry occurs through a greenfield investment. As a result, domestic bank lending rates are lower after greenfield entry. We find empirical support for this prediction for a sample of banks from 10 Eastern European countries for the period 1995–2003.     

Network effects and the dynamics of migration and inequality: Theory and evidence from Mexico

International migration is costly and initially only the middle class of the wealth distribution may have both the means and incentives to migrate, which can increase inequality in the sending community. However, the migration networks formed lower the costs for future migrants, which can in turn lower inequality. This paper shows both theoretically and empirically that wealth has a nonlinear effect on migration, and then examines the empirical evidence for an inverse U-shaped relationship between emigration and inequality in rural sending communities in Mexico. After instrumenting, we find that the overall impact of migration is to reduce inequality across communities with relatively high levels of past migration. We also find some suggestive evidence for an inverse U-shaped relationship among communities with a wider range of migration experiences.     

The spectre of deflation: a review of empirical evidence

Abstract What explains the widespread fear of deflation? This article reviews the history of thought, economic history, and empirical evidence on deflation, with a view to answering this question. It also outlines informally the main effects of deflation in applied monetary models. The main finding is that – for both historical and contemporary deflations – there are many open, empirical questions that could be answered using the tools economists use to study inflation and monetary policy more generally.     

Nonlinear dynamics in exchange rate deviations from the monetary fundamentals: An empirical study

This paper reexamines empirical performance of the monetary exchange rate model with nonlinear dynamics of exchange rate deviation from the monetary fundamentals. First, we apply unit root test of Park and Shintani (2005) to post-Bretton Woods exchange rate data and able to reject the null of unit root deviation from monetary fundamentals against alternative hypothesis of nonlinear stationary process for deutschemark, pound, and Swiss franc. Our empirical results find that exchange rates show high degree of mean-reversion with larger deviation and long periods of overvaluation and undervaluation of dollar. We also find empirical evidence of predictability of the monetary fundamentals at longer horizons.     

Occupational choice, incentives and wealth distribution

We consider a model of occupational choice in large economies where individuals differ in their wealth endowment. Individuals can remain self-employed or engage in productive matches with another individual, i.e., form firms. Matches are subject to a moral hazard problem with limited liability. The division of the gains from such matches is determined by competitive forces. When the incentive problem is asymmetric, matches are typically wealth-heterogeneous, with richer individuals choosing the occupation for which incentives are more important. The utilities attained within a match depend on the wealth distribution and changes in the latter give rise to ‘trickle down’ effects.     

The economics of production systems: Segmentation and skill-biased change

In this paper, the concept of production systems is introduced. I assume a standard thick-market externality together with the idea that higher quality goods also require higher skills from workers. Firms face a trade-off between low-quality goods with low skill-requirements for which the potentially abundant labour force generates strong thick-market externalities and higher quality goods with higher skill-requirements. In equilibrium, the economy is partitioned into production systems, i.e., clusters of firms producing the same quality. The distribution of skills determines the boundaries of the production systems, which in turn determine the wages. In this framework an increase in the supply of skilled workers can induce first higher wages for all workers and then higher wages for the skilled but lower wages for the unskilled. This is consistent with the late 20th century evolution of the US labour market.     

On the long-run wealth distribution in a simple Ramsey model with heterogeneous households

This paper analyzes the long-run wealth distribution in a Ramsey model where individuals have a common rate of time preference but different intertemporal elasticities of substitution. As a result, it is shown that heterogeneity among households in intertemporal substitution is sufficient for the existence of a non-degenerate long-run wealth distribution. We also investigate the properties of the long-run wealth distribution and the transition of capital and consumption using the phase diagram.     

The effects of immigration in frictional labor markets: Theory and empirical evidence from EU countries

Immigrants are newcomers in a labor market. As a consequence, they lack host-country-specific labor market knowledge and other country-specific and not directly productive valuable assets affecting their relative bargaining position with employers. We introduce this simple observation into a search and matching model of the labor market and show that immigrants increase the employment prospects of competing natives. To test the predictions of our model, we exploit yearly variations between 1998 and 2004 in the share of immigrants within occupations in 13 European countries. We identify the impact of immigrants on natives׳ employment rate using an instrumental variable strategy based on historical settlement patterns across host countries and occupations by origin country. We find that natives׳ employment rate increases in occupations and sectors receiving more immigrants. Moreover, we show that this effect varies depending on immigrants׳ characteristics and on host country labor market institutions which affect relative reservation wages.     

Innis Lecture: Equity and equality

Abstract Is horizontal equity (HE) the ‘most widely accepted principle of equity’? Or does it stand in ‘opposition to the advancement of human welfare’? This paper argues that the case for the HE principle is not as straightforward as is usually thought and that it requires advanced notions of justice and well‐being. The most likely ethical basis for HE appears to combine a Rawlsian maximin principle and a view of well‐being that allows for relative local comparison effects. The paper also explores some of the dimensions of equality and well‐being along which the HE principle can be applied and presents a number of examples showing how HE considerations can provide an important input into policy analysis.     

Consumption dynamics in general equilibrium: A characterisation when markets are incomplete

We introduce a methodology for analysing infinite horizon economies with two agents, one good, and incomplete markets. We provide an example in which an agent's equilibrium consumption is zero eventually with probability one even if she has correct beliefs and is marginally more patient. We then prove the following general result: if markets are effectively incomplete forever then on any equilibrium path on which some agent's consumption is bounded away from zero eventually, the other agent's consumption is zero eventually—so either some agent vanishes, in that she consumes zero eventually, or the consumption of both agents is arbitrarily close to zero infinitely often. Later we show that (a) for most economies in which individual endowments are finite state time homogeneous Markov processes, the consumption of an agent who has a uniformly positive endowment cannot converge to zero and (b) the possibility that an agent vanishes is a robust outcome since for a wide class of economies with incomplete markets, there are equilibria in which an agent's consumption is zero eventually with probability one even though she has correct beliefs as in the example. In sharp contrast to the results in the case studied by Sandroni (2000) [29] and Blume and Easley (2006) [8] where markets are complete, our results show that when markets are incomplete not only can the more patient agent (or the one with more accurate beliefs) be eliminated but there are situations in which neither agent is eliminated.     

Equity home bias,incomplete financial markets,and nominal rigidities

Abstract This paper analyzes optimal portfolio decisions in a monetary open‐economy framework. It is found that market completeness and the specific form of nominal rigidities, namely, nominal price vs. nominal wage rigidities, matter for justifying the observed structure of equity holdings. When markets are complete, sticky prices generate a negative correlation between the non‐diversifiable labour income and the profit of domestic firms with respect to the productivity shocks, which explains why households invest little abroad. In contrast, when markets are incomplete, rigidities in goods prices result in a counterfactual ‘super home bias’, because domestic equities provide a good hedge against not only the labour income risk but also the relative price risk. Wage rigidities, however, have the opposite effect. Therefore, nominal rigidities in both goods prices and wage rates are needed to address the empirical composition of gross equity positions under incomplete markets.     

Co-movement and spillovers: empirical evidence from BRIC equity markets

A higher degree of co-movement and spillover effects among different asset classes undermine portfolio diversification benefits. In this regard, the present study attempts to capture dynamic co-movement and return-volatility spillover effects among the most promising emerging equity markets, i.e. Brazil, Russia, India and China in a multivariate framework by employing VAR-ABEKK and VAR-DCC-AGARCH (1,1) models. To further comprehend the behaviour of the correlation coefficients during the global financial crisis period (2007–2009), heat map and Markov regime switching model (two regimes with a switch at ‘mean’ level only) have been used. The results report that the BRIC equity markets do not share a common stochastic trend in the long run. There is strong evidence of market shocks to volatility, volatility to volatility and negative shocks to volatility spillover effects among the BRIC markets. Overall, the BRIC markets are partially integrated with each other, thereby making them stronger investment candidates.     

Constrained suboptimality in incomplete markets: a general approach and two applications

Summary. In this paper we re-examine generic constrained suboptimality of equilibrium allocations with incomplete numeraire asset markets. We provide a general framework which is capable of resolving some issues left open by the previous literature, and encompasses many kinds of intervention in partially controlled market economies. In particular, we establish generic constrained suboptimality, as studied by Geanakoplos and Polemarchakis, even without an upper bound on the number of households. Moreover, we consider the case where asset markets are left open, and the planner can make lump-sum transfers in a limited number of goods. We show that such a perfectly anticipated wealth redistribution policy, though consistent with the assumed incomplete financial structure, is typically effective.

Application of hidden Markov switching moving average model in the stock markets: Theory and empirical evidence

In this paper, we propose a hidden Markov switching moving average model (MS-MA model) to extend the moving average model when the dynamic process of stock returns is predictable. That is, hidden Markov chain can be utilized to better describe the stock return dynamics when moving averages are correlated. Based on the MS-MA model, a recursive method of EM algorithm for parameter estimation is proposed and a numerical analysis is demonstrated. Furthermore, we empirically test the hidden Markov chain model using Dow Jones thirty stocks' data. The empirical results show that the dynamic process of stock returns exhibits MS-MA property, meaning the moving averages of stock returns are correlated. Therefore, the MS-MA model allows us to better understand and to predict stock return stochastic process. This model also helps in pricing equity derivatives.
