National borders matter... where one draws the lines too

The fact that crossing a political border dramatically reduces trade flows has been widely documented in the literature. The increasing number of borders has surprisingly attracted much less attention. The number of independent countries has indeed risen from 72 in 1948 to 192 today. This paper estimates the effect of political disintegration since World War II on the measured growth in world trade. We first show that trade statistics should be considered carefully when assessing globalization over time, since the definition of trade partners varies over time. We document a sizeable resulting accounting artefact, which accounts for 17% of the growth in world trade since 1948. Second, we estimate that political disintegration alone since World War II has raised measured international trade flows by 9% but decreased actual trade flows (including inter-regional trade) by 4%.

Corruption in the Informal Sector: Evidence from West Africa

Abstract Using a unique dataset, this paper analyses the causes and impacts of bribery in the informal sector in West Africa. It investigates the determinants of the incidence of bribery and the magnitude of the bribes actually paid. Our results show that the mechanisms at play are no different than those found for the formal sector by other authors. With respect to the impacts of corruption on a firm’s performance, our findings show that experience of corruption increases business performance, but that this effect is driven by just one category of informal firm: constrained gazelles.
