Mathematical finance plays a vital role in many fields within finance and provides the theories and tools that have been widely used in all areas of finance. Knowledge of mathematics, probability, and statistics is essential to develop finance theories and test their validity through the...

In recent years, there has been increasing interest in whether and how bureaucratic effectiveness contributes to development. Just what makes for an effective bureaucracy and what are the building blocks of state capacity remain subject to debate. This article reviews the arguments connecting...

We address the pitfalls of averaging by exploiting the longitudinal variation in aid to identify sudden and sharp increases in aid flows. Focusing on specific events, we test if aid accelerations correspond to policies and shocks in the recipient country. For a large sample of 145 recipient...

Exploiting Tangshan 1976 - the deadliest earthquake in the 20th century - as a source of exogenous variation, we estimate the long-run effect of a historical shock on contemporary socio-economic outcomes. Cohorts born after the earthquake were not only larger, but exhibit lower school completion...

We use newly digitized records from the U.S. Post Office to study how strengthening state capacity affects public service delivery and innovation in over 2,800 cities between 1875-1905. Exploiting the gradual expansion of a major civil service reform, cities with a reformed postal office...

Using exogenous variation in social proximity generated by an allocation rule, we find that bureaucrats assigned to their home states are perceived to be more corrupt and less able to withstand illegitimate political pressure. Despite this, we observe that home officers are more likely to be...

We link newly-digitized personnel records of the U.S. government for 1907-1921 to census data to study the segregation of the civil service by race under President Woodrow Wilson. Using a difference-in-differences design around Wilson’s inauguration, we find that the introduction of employment...

This paper exploits the idiosyncratic line of contact separating Allied and Soviet troops within East Germany at the end of WWII to study political resistance in a non-democracy. When Nazi Germany surrendered, 40% of what would become the authoritarian German Democratic Republic was initially...
