Deregulation, liberalization and consolidation of the Mexican banking system: Effects on competition

This paper analyzes the evolution of competition in the Mexican banking system in the period 1993-2005, a period of deregulation, liberalization and consolidation of the sector. For this purpose we use two indicators of competition from the theory of industrial organization (the Lerner index and the Panzar and Rosse’s H-statistic). The empirical evidence does not permit us to reject the existence of monopolistic competition. The Lerner index shows a decrease in competitive rivalry in the deposit market and an increase in the loan market, a cross subsidization strategy being observed. The results obtained call into question the effectiveness of the measures implemented hitherto, aimed at increasing the competition of the Mexican banking system.     

Locals, foreigners, and multi-market trading of equities: Intraday evidence from Thailand

We study stock market orders and trades in a developing country, Thailand, where foreign ownership limits partially segment local and foreign investors into two distinct markets. Some foreigners forgo voting rights and distributions to trade on the “local board”, while some locals forgo such benefits and pay a price premium to trade on the “foreign board”. Regardless of nationality, these cross-market traders typically submit orders when liquidity is high, fill orders at relatively beneficial prices, exploit patterns in stock prices across markets, display profitable holding-period returns, and enhance price discovery. This suggests that skilled, informed trading that affects market quality does not depend on trader nationality.     

LONG‐RUN DETERMINANTS OF SAVINGS RATES IN WAEMU COUNTRIES: AN EMPIRICAL ASSESSMENT FROM ARDL BOUNDS TESTING APPROACH

In this paper, we examine the long‐run determinants of savings rates for seven member countries of the West African Economic and Monetary Union over the period 1970–2006. We use the bounds testing approach to cointegration developed by Pesaran et al. This methodology has several advantages with respect to other cointegration tests. The long‐run determinants of savings rate vary across countries. Results reveal that the financial liberalization process undertaken at the end of 1989 and the existing monetary policy have not been effective to increase the domestic savings rates within the area.     

A Distributional Analysis of the FairTax Plan: Annual and Lifetime Income Considerations

Dissatisfaction with the current federal tax system is fostering serious interest in the FairTax Plan, which would replace most of the federal taxes with a national retail sales tax. The FairTax is promoted as being progressive, but there is considerable skepticism of this claim. We examine the distributional effects of the FairTax, as well as the current system it intends to replace, under both annual income and lifetime income approaches. Global measures of progressivity suggest that the current federal tax system is progressive while the FairTax is regressive. Our results are also robust to different assumptions used for estimation.     

Vertical foreign direct investment: Evidence from Japanese and U.S. multinational enterprises

Foreign direct investment (FDI) in developing countries has increased since the 1990s, but there is mixed evidence of vertical FDI associated with factor-seeking motives. This paper estimates the vertical motive of offshore production by multinational enterprises (MNEs) by exploiting past schooling characteristics as instruments for skilled-labor abundance in a host country. Using panel data on Japanese and U.S. MNEs in the 1990s, I find that skilled-labor abundance has a significantly negative impact on sales of manufacturing foreign affiliate only for Japanese MNEs. The results suggest that vertical FDI activity was more prevalent in Japanese MNEs than U.S. MNEs. A plausible explanation is that Japanese MNEs might be more vertically integrated with their offshore production than U.S. MNEs. A difference in foreign outsourcing activities could generate the observed deviation between Japanese and U.S. MNEs.     

Financial openness,market structure and private credit: An empirical investigation

Consistent with recent theoretical models, this paper finds that financial openness has a positive effect on private credit in economies characterized by a competitive banking sector, but that this effect vanishes and even becomes negative in economies with imperfect banking competition.     

Have the returns to education really increased in Vietnam? Wage versus employment effect

Many studies have analyzed changes in the returns to education in globalizing economies using the Mincerian framework. These studies have typically estimated the returns to education in terms of changes in wages rather than employment, effectively ignoring the fact that during globalization not only wages but also employment patterns are affected. In this paper we use four large-scale representative household surveys from the transition economy Vietnam for the period 1998–2006 to estimate the returns to education taking into account both changes in wages and employment. The results show that the estimated increases in returns to education are lower once changes in employment patterns are taken into account.     

Some Marginalist Intuition Concerning the Optimal Commodity Tax Problem

The author offers a simple intuition that can be exploited to derive and to help interpret some canonical results in the theory of optimal commodity taxation. He develops and explores the principle that the marginal social welfare loss per last unit of tax revenue generated be equalized across tax instruments. A simple two-consumer, two-taxed-commodity economy is used to explore how this intuition can be used to derive the famous inverse elasticity rule, as well as the modifications and extensions needed to account for the redistributive effects of commodity taxes.     

Optimal education and pensions in an endogenous growth model

In OLG economies with life-cycle saving and exogenous growth, competitive equilibria in general fail to achieve optimality because individuals accumulate amounts of physical capital that differ from the one that maximizes welfare along a balanced growth path (the Golden Rule). With human capital, a second potential source of departure from optimality arises, related to education decisions. We propose to recover the Golden Rule of physical and also human capital accumulation. We characterize the optimal policy to decentralize the Golden Rule balanced growth path when there are no constraints for individuals to finance their education investments, and show that it involves education taxes. Also, when the government subsidizes the repayment of education loans, optimal pensions are positive.     

Optimal contracting with dynastic altruism: Family size and per capita consumption

We use a Barro–Becker model of endogenous fertility, in which parents are subject to idiosyncratic shocks that are private information (either to labor productivity or taste for leisure), to study the efficient degree of consumption inequality in the long run. The planner uses the trade-off between family size and future consumption and leisure, to provide incentives for workers to reveal their shocks. We show that in this environment, the optimal dynamic contract no longer features immiseration in consumption. We also discuss the implications of the model on the long run properties of family size in the optimal contract and show that the long run trend in dynasty size can be either positive or negative depending on parameters.
