This Paper estimates the effect on international trade of multilateral trade agreements: the World Trade Organization (WTO), its predecessor the Generalized Agreement on Tariffs and Trade (GATT), and the Generalized System of Preferences (GSP) extended from rich countries to developing...

This Paper estimates the effect on international trade of three multilateral organizations intended to increase trade: 1) the World Trade Organization (WTO) and its predecessor the Generalized Agreement on Tariffs and Trade (GATT); 2) the International Monetary Fund (IMF); and 3) the...

The Doha multilateral round of trade negotiations sponsored by the WTO has been dragging on for over a decade, with no end in sight. In this short paper we assess empirically what determines the duration of trade negotiations, focusing on the span between the start of trade talks and their...

This Paper uses 67 measures of trade policy and trade liberalization to ask if membership in the World Trade Organization (WTO) and its predecessor the General Agreement on Tariffs and Trade (GATT) is associated with more liberal trade policy. Almost no measures of trade policy are significantly...

This paper investigates whether cannabis use leads to worse mental health. To do so, we account for common unobserved factors affecting mental health and cannabis consumption by modeling mental health jointly with the dynamics of cannabis use. Our main finding is that using cannabis increases...

In this paper we use individual level data from the Australian National Drug Strategy Household Survey to study the relationship between initiation into cannabis use and educational attainment. Using instrumental variable estimation and bivariate duration analysis we find that those initiating...

We investigate the determinants of the support for cannabis legalization finding a causal effect of personal experience with cannabis use. Current and past cannabis users are more in favor of legalization. We relate this to self-interest and inside information about potential dangers of cannabis...

In the Netherlands cannabis use is quasi-legalized. Small quantities of cannabis can be bought in cannabis-shops. We investigate how the distance to the nearest cannabis-shop affects the age of onset of cannabis use. We use a Mixed Proportional Hazard rate framework to take account of observable...

Cannabis is the most popular illegal drug. Its legal status is typically justified on the grounds that cannabis use has harmful consequences. Empirically investigating this issue has been a fertile topic for research in recent times. We provide an overview of this literature, focusing on studies...

This paper uses duration models and self-reported cannabis histories from young Australians to study the dynamics of cannabis use. We find that low cannabis prices are associated with early initiation into cannabis use. While the decision to quit does not appear to be directly influenced by...
