In this paper we study the effect of labour market rigidity on the impact of exchange rate shocks on employment. We use a panel dataset comprising 22 manufacturing sectors across 23 OECD countries. In our econometric model, the impact of exchange rate fluctuations on sectoral employment is mediated by the degree of openness and by a measure of labour market rigidity: the OECD’s employment protection legislation index. Our results suggest that greater labour market rigidity reduces the impact of exchange rate shocks on employment. This effect is statistically significant for low-technology sectors.

This paper estimates the employer-size wage effect on returns to unobservable skills and measured human capital variables using a novel methodology that allows us to estimate a high number of interactions between unobserved effects and firm size. Our results show that in large firms, returns to ability tend to be smaller than in small firms.

Real exchange rate movements are important drivers of the reallocation of resources between sectors of the economy. Economic theory suggests that the impact of exchange rates should vary with the degree of exposure to international competition and with the technology level. We show that both the degree of openness and the technology level mediate the impact of exchange rate movements on labour market developments. According to our estimations, whereas employment in high technology sectors seems to be relatively immune to changes in real exchange rates, these appear to have sizable and signiffcant effects on highly open low-technology sectors. The analysis of job  flows suggests that the impact of exchange rates on these sectors occurs through employment destruction.

In this paper, we compute and compare aggregate and sector-specific exchange rate indexes for the Portuguese economy. We find that  lternative effective exchange rate indexes are very similar between them. We also find that sector-specific effective exchange rates are strongly correlated with aggregate indexes. Nevertheless, we show that sector-specific exchange rates are more informative than aggregate exchange rates in explaining changes in employment: whereas aggregate indexes are statistically insignificant in employment equations, regressions using sector-specific exchange rate indexes show a statistically significant and economically large effect of exchange rates on employment.

This paper characterizes and evaluates the student allocation in the Portuguese public higher education system. It describes the supply and demand sides of the system by looking at the numerus clausus across areas of study and institutions, institutions’ degree of diversity, and performance and adjustment indicators based on students’ revealed preferences. Performance indicators quantify the adequacy between demand and supply, across institutions and fields of study, and gauge the performance of public higher education institutions in the competition for candidates. Adjustment indicators allow us to predict the potential impact of changes in higher education regulations on student allocation and its stability. According to these indicators, such changes could result in an expansion for some institutions and fields of study, whereas other institutions might face a reduction.

Using linked employer-employee data for Portugal, we explore an amendment to the minimum wage law which increased from 75% to 100% of the full minimum wage applied to employees younger than 18. Our results show a widening of the gender wage gap following the amendment: the wage gap for minors increased 2.7 percentage points more than for other groups. This change was mainly determined by a redistribution of fringe benefits and
overtime payments. We discuss three possible sources of redistribution: (i) a change in the skill composition of the working males and females after the increase in the minimum wage,
(ii) industrial differences in response to the changes in the wage floor, and (iii) discrimination. Estimations support the second channel as the main contributing factor, while possible discrimination effects cannot be eliminated.

In this paper, we explore empirically the role of openness, technology and labour market rigidity in the determination of the effect of the exchange rate on employment in Portugal. We develop an index that allows us to measure labour market flexibility at the sector level. This index shows that labour market flexibility has been increasing in all manufacturing sectors and that the labour market in high technology sectors is more flexible than in low technology sectors. We use this index in the estimation of an employment regression, focusing on the effect of exchange rate movements. Our estimates indicate that employment in low-technology sectors, with a high degree of trade openness and facing less rigidity in the labour market are more sensitive to movements in exchange rates.
