Wealth in Latin America: Evidence from Chile,Colombia, Mexico and Uruguay

Drawing on recently-available microdata from financial surveys, this paper presents harmonized indicators for household wealth, its components, and its determinants in four Latin American countries (Chile, Colombia, Mexico and Uruguay), using Spain as a comparison benchmark. The paper analyzes the relationship between wealth indicators and sociodemographic characteristics of household heads (age, education, gender, marital status). For Uruguay, we are also able to analyze wealth patterns and intergenerational mobility (inheritance, family businesses and parental education).     

Expansions and contractions in Brazil, Colombia and Mexico: A view through nonlinear models

The study of asymmetric behavior of macroeconomic variables over business cycles has had a long tradition in economics. In this present work, we find evidence in favor of the hypothesis of having a STAR-type nonlinear asymmetric behavior of the economic activity, over the last two decades, in three Latin American countries: Brazil, Colombia, and Mexico. For Chile and Venezuela, the null hypothesis of a linear process could not be rejected under the method established by Granger and Teräsvirta [Granger, C.W.J., Teräsvirta, T., 1993. Modelling Nonlinear Relationships. Oxford University Press, New York]. Economic activity is proxied by monthly based industrial production indexes. Evidence of asymmetric behavior is also found according to the generalized impulse response functions analysis for the three countries.     

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 dynamics of parallel economies. Measuring the informal sector in Mexico

The existence of parallel economies that operate in the shadows of informality within most Latin American countries is widely recognized by the economic literature. However, its composition, size and effects on economic growth are still open questions. In this paper, we estimate the size and the evolution of the Mexican informal economy in the last three decades using a vector error correction model. In addition to the standard explanatory variables traditionally used in the currency demand approach, we include remittances given their relevance in the Mexican economic system. The results indicate that informality prior to the late 1980s accounted for at least two thirds of GDP, while stabilizing around one third of GDP in the last decade. Furthermore, our estimates provide evidence of a positive long-run relationship between informality and economic growth.     

On the dynamics of inequality

The dynamics of inequality are studied in a model of human capital accumulation with credit constraints. This model admits a multiplicity of steady state skill ratios that exhibit varying degrees of inequality across households. The main result studies equilibrium paths. It is shown that an equilibrium sequence of skill ratios must converge monotonically to the smallest steady state that exceeds the initial ratio for that sequence. Convergence is “gradual" in that the steady state is not achieved in finite time. On the other hand, if the initial skill ratio exceeds the largest steady state, convergence to a steady state is immediate.This paper is based on unpublished notes from 1990; see http://www.econ.nyu.edu/user/debraj/DevEcon/Notes/incdist.pdf. Two considerations suggest that these results may be worth reporting in print. First, the existence of a sizeable recent literature indicates that these relatively early notes may have value outside a filing cabinet or a private webpage. Second, Mukul Majumdar’s own research on economic growth with a nonconvex technology is an even earlier precursor to some of this literature, so the current outlet – a special issue in his honor – seems appropriate. Conversations with Glenn Loury simplified the proof of the main result. I thank Dilip Mookherjee for many useful discussions, and two anonymous referees for helpful comments on an earlier draft. Funding from the National Science Foundation under grant number 0241070 is acknowledged. This paper is dedicated with much affection and warm admiration to Mukul Majumdar – or to Mukulda, as I always think of him – on the occasion of his 60th birthday.     

On the real effects of inflation and inflation uncertainty in Mexico

We estimate an augmented multivariate GARCH-M model of inflation and output growth for Mexico at business cycle frequencies. The main findings are: (1) inflation uncertainty has a negative and significant effect on growth; (2) once the effect of inflation uncertainty is accounted for, lagged inflation does not have a direct negative effect on output growth; (3) However as predicted by Friedman and Ball, higher average inflation raises inflation uncertainty, and the overall net effect of average inflation on output growth in Mexico is negative. That is, average inflation is harmful to Mexican growth due to its impact on inflation uncertainty. (4) The Mexican Presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth.     

On the dynamics of profit-led and wage-led growth

This paper examines how variable output and profit share jointlydetermine investment and saving, while the difference betweeninvestment and saving drives the changes in output and profitshare. Analysis of the resulting pair of differential equationsyields novel implications for the multiplier process. In thismore general framework a number of separate strands of the Keynesian-inspiredliterature can be understood. In particular, the model incorporatesboth forced saving and profit squeeze to analyse the stabilityof the dynamical system, and brings out the complex relationbetween in and out-of-equilibrium profit-led and wage-led regimes.     

On the dynamics of international inflation

We investigate the dynamic properties of inflation in 20 OECD countries with a novel approach based on the autocorrelation function. We find evidence in favor of long memory and nonlinearity. Linear autoregressive models are shown to be misspecified.     

On the behavioral and rational foundations of economic dynamics

Existing uncertainties about the correct explanations for economic growth and business cycles cannot be settled by aggregative analysis within the neoclassical framework. Current disputes in theory rest largely on ad hoc, casually empirical, assumptions about departures from perfect rationality under uncertainty. Such disputes can only be settled by painstaking microeconomic empirical study of human decision making and problem solving. Microeconomic research of the kinds that are required can receive powerful guidance from the theories of human thinking that have been developed and tested over the past twenty five years by cognitive psychologists.     

On the dynamics of inequality in the transition

Inequality has increased in many of the transition economies. At the same time, spending on education has declined. In this paper we survey the factors driving these changes. We then set up a small general equilibrium model to simulate the effect of different policy choices on the path of inequality over the transition. We show that the policies selected in Central Europe engender a relatively rapid spike in inequality but with a Kuznets curve. In the simulations that broadly capture features of the policy regime dominating in Russia and the FSU, we find no Kuznets curve. We then turn to the longer run and look at the way in which both trade liberalization and technological and organizational change are likely to affect the relative demand for types of labour. We show how substantial technological and organizational change - obvious features of transition - can result in raising inequality. Persistence in inequality can be expected to depend critically on the pace at which the acquisition of skills takes place in the economy - and, hence, on the evolution of the educational system. As such, policies aimed at raising adaptability - such as quality educational systems - can be expected to dampen the increase in wage inequality.     

加工贸易:发展动因与提升空间

加工贸易是以保税方式从国外进口原辅材料或中间产品,经加工为成品后再出口的经济活动,是一种将进口与出口相结合的海关保税业务.据海关统计,从1980年到2005年,我国加工贸易进出口额扩大了412倍,年均增长27.3%,在进出口总额中的比重由4.4%增加到48.6%;同期加工贸易出口扩大了292倍,年均增长25.5%,在出口总额中的比重由7.8%增加到54.7%.加工贸易的这种超常规发展决不是偶然的,而是有着深刻的社会背景和国际背景.     

On the dynamics of renewable resource harvesting and pollution control

The paper presents a dynamic partial equilibrium model which combines optimal renewable resource harvesting and optimal pollution control. Pollution accumulates as a slowly decaying stock and is assumed to affect the growth and the quality of the renewable resource stock. The aim is to maximize a social welfare functional which gives the present value of the difference between natural resource benefits and pollution control costs. The existence, uniqueness and the dynamic properties of the steady states are investigated. The analysis also gives a general result concerning the steady state of any two state variable optimal control problems.     

On the dynamics of a three-sector growth model

Uzawa’s two-sector growth model is extended into a three-sector model, where the labor growth rate is variable and bounded over time. The solution of this economic system is determined, as well as its long-run growth and asymptotic stability are investigated.      

On the disequilibrium dynamics of sequential monetary economies

The purpose of this paper is to study the dynamic behavior of a sequential monetary exchange economy. Transactions take place sequentially against non-equilibrium prices, there is quantity rationing, and credit or cash are the only means of exchange. Agents have optimistic or pessimistic expectations about quantity constraints that represent their beliefs about future trading opportunities.In the credit model the agents incur debts along the transition path towards equilibrium, while in the cash-in-advance model convergence takes place without the occurrence of any debts or claims. The credit mechanism is shown to act as a ‘soft’ correction mechanism on credit fluctuations, while the cash-in-advance constraint acts as a ‘hard’ negative feedback effect driving the prices back towards a neighborhood of a monetary cash-in-advance equilibrium.     

On the persistence of prices in Mexico: a fractional integration approach

A relevant yet often overlooked characteristic of the inflation rate is its mean-reverting property. If a series has this feature, shocks eventually dissipate, whereas if it does not, they have a permanent effect on the series. The usual I(1) versus I(0) dichotomy in time-series econometrics goes only so far towards disentangling this issue. By employing a methodology that estimates the persistence of inflation by allowing (i) fractional integration and (ii) persistence and level shifts in the series, we aim to define whether it is stationary and/or mean reverting and, if so, during which periods. The results of our analysis for the period 1987–2015 are threefold: firstly, inflation in the eighties and nineties should be seen as a highly persistent yet mean-reverting process (not a random walk); secondly, inflation remained mean reverting, though became a short-memory (less persistent) process around the date of the implementation of the inflation-targeting framework of 2001; thirdly, during the later phase, the level of inflation also decreased and is now within the inflation target range set by Banco de México, namely 3 per cent with an interval of ±1 percentage point.     

On the dynamics of inflation persistence around the world

We study the dynamics of inflation persistence in 45 countries for the period 1960–2008 using a recently developed test for multiple changes in persistence, which decomposes the sample information between adjacent I (0) and I (1) periods. We find that: (i) inflation persistence and average inflation tend to fall and rise at the same time; (ii) in some countries there are changes in the level of inflation which do not seem to be related to changes in inflation persistence; (iii) around half of the countries analyzed do not present any burst of I (1) behavior, and hence have stationary inflation throughout; (iv) for the other half, we detect switches of the type I (0) ? I (1) ? I (0), hence, inflation persistence, when it has occurred, has been temporal; and, (v) for about half of the countries in which inflation has presented I (1) behavior, persistent inflation lasted more than a decade. In addition, we find that in the last 50 years there have been mainly two episodes where long bursts of I (1) inflation took place simultaneously among groups of countries. In general, the “Great Inflation” occurred during the seventies and eighties in advanced economies, whereas it occurred during the eighties and nineties in emerging economies, particularly in Latin America.     

On the dynamics of interstate migration: Migration costs and self-selection

This paper develops a dynamic structural model of migration decisions that is aggregated to describe the behavior of interregional migration. Our structural approach allows us to deal with dynamic self-selection problems that arise from the endogeneity of location choice and the persistence of migration incentives. The self-selection problem is solved by keeping track of the distribution of migration incentives over time. This econometric treatment has important consequences for the estimation of structural parameters such as migration costs. For US interstate migration, we obtain a cost estimate of roughly two-thirds of an average annual household income. We also show that the treatment of income persistence has important consequences for comparative statics of the model as well as microeconomic age patterns of migration.     

On complex dynamics of monopoly market

The equilibrium state of a bounded rational monopolist model is studied in this paper. It is assumed that the entire demand function is considered based on some market experiments to produce a quantity which maximizes profit. The stability of equilibrium state of the model is discussed. In addition, some complex dynamical behaviours of the model are illustrated.
