The trade creation effect of immigrants: evidence from the remarkable case of Spain

Abstract This paper investigates the immigration‐trade link using data on individual exporting transactions and immigrants in Spanish provinces between 1995 and 2008. We quantify the impact of new immigrants on the extensive margin (number of transactions) and intensive margin (average value per transaction) of exports. We find that immigrants significantly increase exports and that the effect is almost entirely due to an increase in the extensive margin. Consistent with the idea that immigrants reduce the fixed cost of exporting, we find stronger effects for differentiated goods and for countries that are culturally distant from Spain.

The transmission of financial shocks in an estimated DSGE model with housing and banking

We develop a dynamic stochastic general equilibrium (DSGE) model with housing and banking to study the transmission of financial shocks between the financial and real sectors. A deterioration in the bank's balance sheet induced by financial shocks could have amplified and persistent impacts on real activities. The amplification of the shocks are originated from financial frictions tied to households and banks. We find that a disruption in bank net worth initiated by capital quality shocks generates a decline in household loans, house prices and output. Bank liquidity shocks also have negative effects on these variables. Housing preference shocks could generate a positive comovement between house prices and output. All these findings are qualitatively consistent with empirical evidence, suggesting that these financial shocks are critical to the dynamics of house prices and other macroeconomic variables.     

Modeling input–output impacts with substitutions in the household sector: A numerical example

Although there have been many elaborations of the basic input–output approach, including multi-regional models, dynamic models, models with variable coefficients, supply-side models, etc., these approaches all have the same limitation. The fixed-coefficients production function assumptions ignore substitutions in response to price changes that can be expected to accompany most shocks— skipping over the heart and soul of market economics. This research note suggests a simple approach to estimating new technical coefficients matrices after a shock so that the consequences of short-term substitution effects can be studied. Given a reduction in income (as reflected in the value added row), households are likely to make substitutions, reducing their final demand by less than the application of base-year I–O coefficients would indicate. But if ex post changed income and consumption can be observed, the application of RAS procedures can generate an appropriately modified A matrix. The resulting set of interdependent substitutions that occurred can be identified. Due to some well known limits in applying the traditional RAS approach, we reformatted it and suggest a new economic model that can link coefficient adjustments to degrees of a priori substitutability and complementarity. Based on this resolution, we look forward to detailed studies of specific coefficients and how they evolve over the short term.     

Detecting periods of exuberance: A look at the role of aggregation with an application to house prices

The recently developed SADF and GSADF unit root tests of Phillips and Yu (2011) and Phillips et al. (2015a,b) have become popular in the literature for detecting exuberance in asset prices. In this paper, we examine through simulation experiments the effect of cross-sectional aggregation on the power properties of these tests. The simulation design considered is based on simulated data and actual housing data for both U.S. metropolitan areas and international housing markets and thus allows us to draw conclusions for different levels of aggregation. Our findings suggest that aggregation lowers the power of both the SADF and GSADF tests. The effect, however, is much larger for the SADF test. We also provide evidence that tests based on panel data techniques, namely the panel GSADF test recently proposed by Pavlidis et al. (2016), can perform substantially better than univariate tests applied to aggregated series. Furthermore, we also illustrate the date-stamping procedure under the univariate/panel GSADF procedure uncovering novel evidence on the role of interest rates and policy uncertainty as factors explaining episodes of widespread mildly explosive dynamics in housing markets.     

Evolution of the Corporation in the United States: Stabilized Scarcity and Vested Interests

The widening of markets beginning in the late nineteenth century in the United States involved changes in the financial and legal institutions supporting production for large-scale markets. The evolution of the corporation under these circumstances reflects the role of the legal system in formulation of formal rules which favor vested interests. As Thorstein Veblen said, “A constitutional government is a business government.”

This article examines the co-evolution of the legal system and the economic system as they relate to the merger movement at the turn of the twentieth century, the increased use of the corporate form, and the emphasis on pecuniary values over production to secure stabilized scarcity in the midst of cutthroat competition and deflation. The resultant financialization of the economy which continues today was reinforced by such legal rules as the Fourteenth Amendment’s protection of property, including intangible property, and the Rule of Reason accommodating some instances of monopolization. These stabilization policies have secured the rentiers’ return at the cost of the long term health of the national economy. John R. Commons’ observations on artificial selection and the use of law to make capitalism better offer a solution through laws regulating the detrimental aspects of financialization.     

Regional distribution and dynamics of human capital in China 1985–2014

This study investigates the regional distribution and dynamics of human capital in China. We develop a new comprehensive human capital measure based on the Jorgenson-Fraumeni (J-F) lifetime income framework, in addition to using the traditional education-based human capital measures. We find that the new J-F human capital measure reflects more closely the regional economic disparity than the education-based measures. We also conduct a Divisia decomposition analysis to investigate the contributions of different factors to the quantity and quality growth of human capital and to regional disparity. Our results show that the regional human capital gaps in China are enlarging in general. Education and urbanization contribute most to human capital growth, while population aging shows a strong negative effect. Our estimates create a new provincial level human capital panel dataset from 1985 to 2014, which is useful for empirical work and policy analysis.     

The role of intergenerational mobility in internal migration

This paper investigates the role of intergenerational mobility in the internal migration decisions of families. The geographic variation in intergenerational mobility suggests that if parents value their children's human capital accumulation and future outcomes, they would have an incentive to move to areas with a higher upward mobility. To identify the effect of intergenerational mobility on family migration, we first use an instrumental variable approach, based on a heteroskedastic covariance restriction, which addresses measurement-error and omitted-variable biases. Then, we apply the semiparametric maximum score estimation method to our empirical model, which yields a consistent estimator when families' choice sets are partially observed. We find that highly educated families with school-aged children choose areas that favor upward mobility. Our welfare analysis indicates that a unit increase in the absolute upward mobility of a commuting zone is equivalent to approximately a $722 higher mean wage in the local labor market.     

Natural resources,economic growth and geography

Worldwide materials extraction increased by a factor of 8.4 over the course of the 20th century. In the meantime, global GDP and population increased by factors of about 22 and 4, respectively. This reveals that one of the key factors driving the increase in the exploitation of the resources was the growth in world population, although mitigated by the reduction in the intensity in the use of the resources in production. In this paper, we present a model that combines the theory of endogenous growth and the economy of natural resources, but taking into account the geographical distribution of economic activity. Indeed, the New Economic Geography provides insights about two elements that, although speeding up GDP growth, can curb the pressure on natural resources, namely the reduction in transports costs and a boost to pace of innovation.
