Distributional comparative statics with heterogeneous agents

We propose a formal way to systematically study the differential effects of exogenous shocks in economic models with heterogeneous agents. Our setting applies to models that can be rephrased as "competition for market shares" in a broad sense. We show that even in presence of any number of arbitrarily heterogeneous agents, a single recursion relation characterizes the…

Health and skill formation in early childhood

This paper analyzes the developmental origins and the evolution of health, cognitive, and socio-emotional skills during early childhood, from age 0 to 5. We explicitly model the dynamic interactions of health with the child’s behavior and cognitive skills, as well as the role of parental investment. A dynamic factor model corrects for the presence of measurement error in the proxy…

Leverage and beliefs: personal experience and risk-taking in margin lending

What determines risk-bearing capacity and the amount of leverage in financial markets? Using unique archival data on collateralized lending, we show that personal experience can affect individual risk-taking and aggregate leverage. When an investor syndicate speculating in Amsterdam in 1772 went bankrupt, many lenders were exposed. In the end, none of them actually lost money.…

The multiplex network of EU lobby organizations

The practice of lobbying in the interest of economic or social groups plays an important role in the policy making process of most economies. We carry out a multi-level network analysis of the relations among lobbying organizations in the EU transparency register, focusing on the domain of finance and climate. We find that the network centrality of organizations has no simple…

Particle Filtering, Learning, and Smoothing for Mixed-Frequency State-Space Models

We propose a general particle filtering and learning framework for mixed-frequency state-space models. Our mixed-frequency particle methods use a smoother so as to draw the Bayesian in- ference from low-frequency observations. Our forward smoother is simple and efficient, and the sample path degeneracy is negligible with a small lag size. The backward smoother mitigates the sample…

Brain stimulation reveals crucial role of overcoming self-centeredness in self-control

Neurobiological models of self-control predominantly focus on the role of prefrontal brain mechanisms involved in emotion regulation and impulse control. We provide evidence for an entirely different neural mechanism that promotes self-control by overcoming bias for the present self, a mechanism previously thought to be mainly important for interpersonal decision-making. In two…

Pricing contract terms in a crisis: Venezuelan bonds in 2016

As of this writing in June 2016, the markets are predicting Venezuela to be on the brink of default. On June 1, 2016, the 6 month CDS contract traded at about 7000bps which translates into a likelihood of default of over 90%. Our interest in the Venezuelan crisis is that its outstanding sovereign bonds have a unique set of contractual features that, in combination with its near-…

Securitization and lending standards: Evidence from the European wholesale loan market

We assess the effect of securitization activity on banks’ lending rates employing a uniquely detailed dataset from the euro-denominated syndicated loan market. We find that, in the run up to the 2007-2009 crisis banks that were more active at originating asset-backed securities did not price their loans more aggressively (i.e. with narrower lending spreads) than less-active banks.…

The benefits of intervention: birth weights in Basle 1912-1920

To assess the impact of interventions on well-being during war time, we analyze data from the birth records at the university maternity hospital of Basle in the period 1912-1920. Birth weight of children from medium SEP families decreased during the crisis years 1918 and 1919, but not for low and high SEP families. A potential explanation is access to food: while high SEP families…

Changing cultural attitudes towards female genital cutting

As globalization brings people with incompatible attitudes into contact, cultural conflicts inevitably arise. Little is known about how to mitigate conflict and about how the conflicts that occur can shape the cultural evolution of the groups involved. Female genital cutting is a prominent example1, 2, 3. Governments and international agencies have promoted the abandonment of cutting…

The order of knowledge and robust action. how to deal with economic uncertainty?

Uncertainty in economics is generated by “nature” but also by the model we use to “produce the future”. The production of the future comprises besides the allocation of resources on different instruments (technologies, financial products) also the design of the instruments. Specialization and diversification considerations point to the advantages of targeting instruments to a rich…

Macroeconomic risk in exchange rates: three empirical essays

This introductory umbrella chapter interlinks the three essays of this dissertation thesis and explains their stance towards the economic discipline. The essays focus on two key exchange rate puzzles, which are the forward premium puzzle of Fama (1984) and the consumption real exchange rate correlation puzzle of Backus and Smith (1993). As regards the first puzzle, this thesis…

Partial adaptation of obtained and observed value signals preserves information about gains and losses

Given that the range of rewarding and punishing outcomes of actions is large but neural coding capacity is limited, efficient processing of outcomes by the brain is necessary. One mechanism to increase efficiency is to rescale neural output to the range of outcomes expected in the current context, and process only experienced deviations from this expectation. However, this mechanism…
