Modeling and forecasting dynamic (or time-varying) covariance matrices has many important applications in finance, such as Markowitz portfolio selection. A popular tool to this end are multivariate GARCH models. Historically, such models did not perform well in large dimensions due to the...

This paper studies the dynamic construction of a blockchain by competitive miners. In contrast to the literature, we assume a finite time horizon. Moreover, miners are rewarded for blocks that eventually become part of the longest chain. It is shown that popular mining strategies such as...

Intuitive decision making has a large and often negative impact in economic decisions, but its measurement and quantification remains challenging. Following research from psychology, behavioral economists have often attempted to causally manipulate the balance of intuition and deliberation by...

We use surveys, laboratory experiments and administrative labor-market data to study how heterogeneity in the perceived immorality of work and in workers' aversion to acting immorally interact to impact labor market outcomes. Specifically, we investigate whether those individuals least concerned...

This paper develops a dynamic general equilibrium model with two currencies to study the effect of negative interest rates on domestic money demand and exchange rates. Money demand for a currency depends on the relative ratio of the money market rate and the deposit rate of the central bank. If...

Poverty focuses attention on present needs. Does that mean that poor parents respond inefficiently to future returns on investments in their children's human capital - even when they would have the financial means to invest optimally? We study this question in the context of an educational...

Working memory capacity is thought to play an important role for a wide range of cognitive and non-cognitive skills such as fluid intelligence, math, reading, the inhibition of pre-potent impulses or more general self-regulation abilities. Because these abilities substantially affect...

Do firms seek to make the market transparent,or do they confuse the consumers in their product perceptions? We show that the answer to this question depends decisively on preference heterogeneity. Contrary to the well-studied case of homogeneous goods, confusion is not necessarily an equilibrium...

This paper studies (non-)equivalence of collateralized credit and asset sale for information-sensitive assets in over-the-counter markets. A signaling game refined by the undefeated equilibrium endogenizes the choice between pooling and separating offers and addresses the payment puzzle. The...

We study subgame-perfect implementation (SPI) mechanisms that have been proposed as a solution to incomplete contracting problems. We show that these mechanisms — which are based on off-equilibrium arbitration clauses that impose large fines for lying and the inappropriate use of arbitration...
