The purpose of this paper is to study the relationship between job mobility and wage mobility. One of the main points of this paper is that job mobility is not necessarily bad. Job mobility might be the quickest way in which workers can advance in their careers and move up in the wage structure....

This paper studies the effect that mother's education as knowledge has on child health using height for age as health measure. Using cross sectional data from de 1993 South Africa Integrated Household Survey, and health measures form de National Center for Health Statistics, we find a...

This paper analyses plant entry, total factor productivity growth, average productivity level differentials and turnovers across Colombia's petrochemical industry for the 1974-1998 period. Results show that successful entrants shaped industry productivity and induced plant restructuring among...

A Strand of recent literature shows that a reform of import tariff (export tax) and consumption tax (production tax) that keeps consumer (producer) price unchanged cnhances welfare and increases revenue under plausible conditions. We demonstrate that the results derived so far critically depend...

The economies of the former Soviet Bloc experienced large declines in output during the decade of transition which began with the collapse of the Soviet Union in 1991. Yet there are many reasons to believe that measured output and official deflators provide a poor proxy for the change in real...

This paper extends the linear lasso estimators to non-linear case. We are especially interested in GMM type of Lasso estimators. Lasso estimators are generalization of ridge regression in least squares. With this setup we can deal with identification problem introduced by weak instruments. When...

In examining the likely consequences of nonsense relationship, Granger and Newbold (1974) made it clear that the differencing is not the universal sure solution to the problem of spurious regression models. This has prompted the discovery of the cointegration regression estimation by Engle and...

The use of the Beveridge Nelson decomposition in macroeconomic analysis involves the truncation and estimation of infinite weighted sums of random variables, whereas the single source of error (SSE) state space approach provides a simple and effective framework that leads to exactly the same...

In many countries we observe a gap between macroeconomic and microeconomic statistics. In order to explain the underreporting observed in microeconomic statistics, the present paper tests the misreporting hypothesis through the double hurdle model. The misreporting hypothesis is based on some...
