It obtains an elasticity of substitution below one and identifies different rates of factor-augmenting technical progress. The results support for labor-saving innovations hypothesis for the Spanish case. Nevertheless, they do not support a relationship between the elasticity of substitution and the initial regional capital per worker. The results do not change if labor is adjusted by human capital. 2022-12-06T00:00:00+00:00 Copyright (c) 2022 Estudios de Economía Intellectual property rights and North-South trade: Exports vs. foreign direct investment 2022-12-06T01:54:56+00:00 Quan Dong Juan Carlos Bárcena-Ruiz María Begoña Garzón This paper examines whether a Northern firm prefers to export or to engage in FDI to serve the South. If the firm engages in FDI, its technology is imitated, and a Southern firm enters the market that may sell in both markets. The Northern firm may invest to prevent product piracy in the North. The two markets may have different sizes. We find that when the cost of preventing product piracy in the North is great enough: (i) If the Southern market is large enough the Northern firm engages in FDI, allowing piracy in its home market, and the South obtains the greater welfare; (ii) If the Southern market is small enough the Northern firm exports and the government of the South imposes a strong Intellectual Property Rights protection, attracting the Northern firm and improving the welfare of both countries. 2022-12-06T00:00:00+00:00 Copyright (c) 2022 Estudios de Economía Does college make you progre? Evidence from Bolivia 2022-12-06T02:04:49+00:00 Antonio Saravia I examine the association between college education and left-leaning views in Bolivia using novel survey data. My findings suggest that college education is associated with left-leaning social preferences (college-educated individuals favor social equality and a tax system in which not everybody must pay taxes) but right-leaning individual preferences (they favor individual liberty and respect for private property). My results fit the connotation given to terms like progre or socialista caviar commonly used in Latin America to refer to educated individuals who consider themselves progressive, or even socialist, but admit and enjoy the benefits of individual liberty and markets. 2022-12-06T00:00:00+00:00 Copyright (c) 2022 Estudios de Economía Herding behavior in the Chinese stock market and the impact of COVID-19 2022-12-06T02:12:21+00:00 Carlos Maquieira Christian Espinosa-Méndez We analyze herding behavior in the Chinese stock markets in the context of the COVID-19 pandemic using the cross-sectional absolute deviation (CSAD) model proposed by Chang et al. (2000) to detect herding behavior in the time period between January 30, 2001, and June 12, 2020. We consider stock prices for all firms listed (A-shares) on the Shanghai Stock Exchange (SHSE) and Shenzhen Stock Exchange (SZSE) in China. We report the presence of herding behavior during the period under study and that herding behavior becomes stronger after December 31, 2019 (the COVID-19 event date). We also study herding activity in the context of potential asymmetries in market return and volatility states. The results show that when the market return is high and the volatility is low, there is a more predominant herding behavior trend. Our results do not depend on using different time windows. Results do not change when time-varying coefficients are considered using rolling regressions. Other control variables which may be relevant in explaining CSAD do not change the results when included in the estimations. 2022-12-06T00:00:00+00:00 Copyright (c) 2022 Estudios de Economía University credentials and wage differentials in the Argentine productive structure 2022-12-06T02:25:13+00:00 Martín Trombetta Gisella Pascuariello Nicolás Sidicaro Pablo Sonzogni Gisel Trebotic We estimate the wage return of the different university-level educational credentials in Argentina using administrative data for 2019. The results indicate sizeable variability according to the hierarchy of the degree and area of knowledge. Applied Sciences obtain the best results, while the opposite is true for the Humanities. These effects are higher for individuals located in the right tail of the conditional wage distribution. 2022-12-06T00:00:00+00:00 Copyright (c) 2022 Estudios de Economía
