Using the model proposed in Krugman and Taylor’s “Contractionary effects of devaluation” (1978), we examine the macroeconomic effects of shocks to foreign prices. We show that these shocks can be contractionary for two reasons: (i) because they imply a loss of income if an economy has a trade deficit or import prices increase proportionally more than export prices; (ii) because there is a redistribution of income from wages to profits and rent, which leads to a decrease in consumption and output (as the wage earner's propensity to consume is higher than those of profit earners and rentiers). An endogenous reaction of nominal wages to the increase in the price level might lead to even higher increases in prices, but mitigates the negative macroeconomic effects of the foreign price shocks because it reduces their negative distributional effects. If the proportional increase in nominal wages is higher than that of domestic prices, the distributional effect becomes positive. The opposite is the case with markups. If they increase in reaction to higher prices, they contribute to further price increases but they also exacerbate the negative distributional effects. The paper also provides an analytical solution for a general case of the model of Krugman and Taylor.

Fiscal policy is useful as a government instrument for supporting the economy, contributing to an increase in employment, and reducing inequality through more egalitarian income distribution. Over the past 30 years, developing countries have failed to increase their real wages due to the lack of domestic value-added in the era of globalization, where global supply chains are the driving factor for attracting foreign direct investment. Under such circumstances, the role of fiscal policy has become an important factor in creating the necessary conditions for boosting the economy. With the end of commodity-export-led growth, Mexico experienced a moderate reduction of 5 percent in poverty between 2014 and 2018 due to the structural adjustment of social policies and its economic and trade relationship with the United States; during the same period there has been no change in poverty in Argentina, and Brazil has suffered a rise in poverty. Following the global financial crisis, greater attention has been paid to fiscal policy in developed and developing countries—specifically Argentina, Brazil, and Mexico (ABM)—in order to attain macroeconomic stability. One of the consequences of the financial crisis is rising income inequality and its negative effects on economic growth. Over the past decade, fiscal policy has been adopted for the economic recovery. However, the recovery has been accompanied by a decrease in real wages of the middle class. The purpose of the present research is to critically examine the results of fiscal policy in ABM and the United Nations’ 2030 Agenda for Sustainable Development.

This paper describes the application of a semiparametric approach, known as a varying coefficients model (Hastie and Tibshirani 1993), to implement a Oaxaca-Blinder type of decomposition in the presence of self-selection into treatment groups for a continuum of comparison groups. The flexibility of this methodology may allow for detecting heterogeneity of the role of endowment and coefficient effects when analyzing endogenous dose treatments. The methodology is then used to revisit the impact of obesity on wages (Cawley 2004), using body mass index (BMI) as the continuous group variable. The results suggest that body weight does have a negative impact on wages for white women, but the impact decreases for higher BMI levels. For white men, the impact is also negative and significant, but positive for low levels of BMI, which explains why they are not significant in the linear instrumental variables approach.
