We assess the robustness of previous findings on the determinants of terrorism. Using extreme bound analysis, the three most comprehensive terrorism datasets, and focusing on the three most commonly analyzed aspects of terrorist activity, i.e., location, victim, and perpetrator, we re-assess the...

I consider a model in which an asset owner must decide how much to invest in his asset mindful of the fact that an encroacher’s valuation of the asset is increasing in the asset owner’s investment. Due to incomplete property rights, the encroacher and asset owner engage in a contest over the...

We show that the recent rise in Afghan opium production is caused by violent conflicts. Violence destroys roads and irrigation, crucial to alternative crops, and weakens local incentives to rebuild infrastructure and enforce law and order. Exploiting a unique data set, we show that Western...

This paper develops a model of the war against illegal drugs in both producer and consumer countries. The paper studies the trade-off faced by the government of the drug consumer country between prevention policies (aimed at reducing the demand for drugs) and enforcement policies (aimed at...

Anti–money laundering regulations have been centred on the “Know-Your-Customer” rule so far, overlooking the fact that criminal proceedings that need to be laundered are usually represented by cash. This is the first study which tries to provide an answer to the question of how much of...

For the first time we develop a time series of tax evasion (in % of official GDP) for 38 OECD countries over the period 1999 to 2010 based on MIMIC model estimations of the shadow economy. Considering indirect taxation and self-employment as the driving forces of tax evasion, we observe a...

We study compliance dynamics generated by a large set of behavioral rules describing social interaction in a population of agents facing an enforcement authority. When the authority adjusts the auditing probability every period, cycling in cheating-auditing occurs: Intensive monitoring induces...

In this paper the main focus lies on the shadow economy and on work in the shadow. The most influential factors on the shadow economy are tax policies and state regulation. The size of the shadow economy was decreasing over 1999 to 2007 from 34.0% to 31.2% for 161 countries (unweighted average)....

This paper presents the various methods to estimate the size of the shadow economy, their strengths and weaknesses. The purpose of the paper is twofold. Firstly, it demonstrates that no ideal method to estimate the size and development of the shadow economy exists. Because of its flexibility,...

Traditionally banks have used securitization for expanding credit and thus their profitability. It has been well documented that, at least before the 2008 crisis, many banks were keeping a high proportion of the securities that they created on their own balance-sheets. Those securities retained...
