This paper investigates a trade model with many countries, many goods produced in multiple quality versions and non-homothetic preferences. It studies the impact of productivity, population changes and trade costs on the quality composition of exports. The analysis embeds within the same model a series of empirical results about high-income countries specialization and trade in higher quality goods. Product di¤erentiation matters at explaining the volumes of trade quality. High-quality goods exhibiting a high degree of di¤erentiation are traded only by high-income countries. [less ▲]

This paper studies the time slot allocation of flight departures when travelers have a preference for departing on peak times and the number of available peak-time slots is constrained by airport capacities. We show that, compared to public airports, private airports may restrain their supply of peak slots strictly below their capacity levels when they serve airlines that compete to the same destinations. Such an inefficiency takes place in airports that have low per-passenger charges and are not too busy. It does not occur in the absence of competition in destination markets. [less ▲]

This paper examines how the decision to acquire higher education may affect job and marital satisfaction. We propose a theoretical model where individuals decide whether to attend university both for obtaining higher job satisfaction and for meeting potential partners. As the probability of marrying an educated partner increases (due to positive educational assortative matching), the average ability of university students falls, since more (low ability) students are willing to attend university. Two effects can be withdrawn: (i) average job satisfaction decreases, while (ii) marital satisfaction increases. We then test the model using the British Household Panel Survey for years 1996-2008, using a dynamic bivariate model. Consistent with the theoretical predictions, we find that higher education is correlated with lower average job satisfaction. In addition, the higher education of the partner increases marital satisfaction. [less ▲]
