This paper analyzes two econometric tools that are used to evaluate distributional effects, conditional quantile regression (CQR) and unconditional quantile regression (UQR). Our main objective is to shed light on the similarities and differences between these methodologies. An interesting theoretical derivation to connect CQR and UQR is that, for the effect of a continuous covariate, the UQR is a weighted average of the CQR. This imposes clear bounds on the values that UQR coefficients can take and provides a way to detect misspecification. The key here is a match between CQR whose predicted values are the closest to the unconditional quantile. For a binary covariate, however, we derive a new analytical relationship. We illustrate these models using age returns and gender gap in Argentina for 2019 and 2020.

The theoretical literature has not reached a consensus on the effect of PTAs on multilateral liberalization. Empirical studies on this topic have been limited and, like theoretical studies, their results vary. The objective of this study is to find the effect of the Andean Community of Nations on the multilateral liberalization of Peru, by analyzing the variations in the Most Favored Nation (MFN) tariffs applied to non-members as a consequence of the preferential tariff reductions applied by Peru to the members of this PTA. The units of analysis are the tariff lines disaggregated to 6 digits of the Harmonized System for the period 1992-2010. Results show that, for the entire study period, the Andean Community generated a building block. We divided the sample into two sub-periods: 1992-2001 and 2002-2010. For the first period the results show a building block effect; however, for the second half the results changed, and a stumbling block is found. Other variables are also added to observe their effects on changes in external tariffs, such as preferential imports, which, when they present a sizeable preferential margin, cause a reduction in MFN tariffs for the entire sample. Based on these results, we found that the Andean Community did not represent an impediment to multilateral liberalization in Peru.

We present a simple test of spatial autocorrelation based on the skedastic structure of the spatial series. Its distribution function is known for all sample sizes. Moreover, it is very simple to obtain, specially in a case of small samples where the new GQsp test has great power, higher than other alternatives existing in the literature.

PurposeOver the past decades, the global solar photovoltaic (PV) market has experienced an unprecedented development associated with a substantial decline in solar PV module prices. A body of literature has attempted to identify and evaluate the different sources of price variation. However, the impact of international trade on the price of solar PV modules has not yet been empirically examined. This paper contributes to filling this gap in the literature by providing a comprehensive empirical examination on the relationship between international trade and solar PV module prices.Design/methodology/approachThe author uses a sample of 15 countries over the period 2006–2015 and proposes a linear dynamic panel data model based on a new specification, including a number of relevant factors influencing solar PV module prices.FindingsThe empirical analysis reveals that an increase in imports of solar PV cells and modules is associated with a decline in solar PV module prices. This finding suggests that international trade could lead to further price reductions, thus fostering the deployment of solar PV technology. The study reveals several other important findings. Market and technological development are key factors explaining the decline in solar PV module prices. Moreover, government policies such as public budget for R&D in PV and feed-in tariff for solar PV are effective in reducing the price of solar PV modules.Originality/valueThis paper examines the influence of international trade, government policies, market development and technological development on solar PV module prices. The results may be of interest to both academic research and policy analysis.

Using a novel dataset, this article studies the spatial distribution of human capital constraints across 339 municipalities in Bolivia. In particular, five human capital constraints are evaluated: chronic malnutrition in children, non-Spanish speaking population, secondary dropout rate of males, secondary dropout rates of females, and inequality in years of education. Through the lens of principal components, spatial dependence, and regionalization methods, the municipalities are endogenously classified according to their similarity in human capital constraints and geographical location. Results from the spatial dependence analysis indicate the specific location of significant hot spots (high-value clusters) and cold spots (low-value clusters). A regionalization analysis of the constraints indicates that Bolivia can be regionalized into seven or eight geographical regions. The article concludes discussing the potential complementary of these two analyses and their usefulness in identifying the location of policy priorities.

This paper studies the impact of import competition from China on labor outcomes in the Peruvian manufacturing sector in 2001–2010. Using data from the Peruvian Household Survey, we use a two-step procedure to evaluate the impact of the surge in imports from China on the likelihood of having an informal job and on wages in both the formal and informal sectors. On the first step, the results suggest that greater import competition increased—albeit weakly—the likelihood of having an informal job for workers with elementary education. On the second step, we find that the surge in imports from China was detrimental to wages of the least educated individuals with informal jobs—with no education and elementary education—, although we also find that this result is mostly driven by the presence of self-employed among informal workers. We also observe a wage increase among workers with formal jobs and elementary and high school education. These results are robust to the inclusion of different exclusion restrictions and even after accounting for industry-level growth which was strong during the period studied.
