Three Essays in Applied Economics

In this thesis I present three essays that explore various economic situations on strategic choices from different perspectives: the individuals’ strategic decision to work on the informal/formal sector, the US strategic decision on the provision of foreign aid, and the firm’s strategic decision to engage in Corporate Social Respon- sibility (CSR). The first essay presents an analysis on the effect of income taxes and its effect on worker’s transitions towards informality. We find that an increase in average tax rate leads to a statistically significant increase in transitions towards informality for women and those with low incomes. The second essay offers evidence of how patterns of US foreign aid to Latin America differ from aid allocation observed elsewhere. We find that while political institutions and events in recipient countries greatly influence US aid allocations, the ideological orientation of US administrations can explain part of the divergent patters of aid towards Latin America. Finally, the third essay studies two possible mechanisms that affect the deci- sion of a firm to engage in CSR: the role of growth in value added and workers’ preferences. The results suggest that firms engage in CSR in times of economic prosperity; peer effects are increasingly important in a firm’s decision to engage in CSR when the proportion of firms within an industry increases. And finally, I find a weak link between workers’ preferences and a firm’s decision to engage in CSR activities related with diversity.
