Social discounting involves modulation of neural value signals by temporoparietal junction
Most people are generous, but not toward everyone alike: generosity usually declines with social distance between individuals, a phenomenon called social discounting. Despite the pervasiveness of social discounting, social distance between actors has been surprisingly neglected in economic theory and neuroscientific research. We used functional magnetic resonance imaging (fMRI) to...

Collateral requirements and asset prices
Many assets derive their value not only from future cash flows but also from their ability to serve as collateral. In this paper, we investigate this collateral premium and its impact on asset returns in an infinite-horizon general equilibrium model with heterogeneous agents facing col- lateral constraints for borrowing. We document that borrowing against collateral substantially...

Evidence for countercyclical risk aversion: an experiment with financial professionals
A key ingredient of many popular asset pricing models is that investors exhibit countercyclical risk aversion, which helps explain major economic puzzles such as the strong and systematic variation in risk premiums over time and the high volatility of asset prices. There is, however, surprisingly little evidence for this assumption because it is difficult to control for the host of...

Reference points, social norms, and fairness in contract renegotiations
How does an ex-ante contract affect behavior in an ex-post renegotiation game? We address this question in a canonical buyer–seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and economically important
impact on renegotiation behavior that goes beyond the effect of contracts on bargaining...

On the origin of r-concavity and related concepts
In a less widely known contribution, Béla Martos (1966, Hungarian Academy of Sciences) introduced a generalized notion of concavity that is closely related to what is nowadays known as r-concavity in the operations research literature, and that is identical to what is nowadays known as ρ-concavity in the economics literature. The present paper aims at making the original...

The Dynamic Impact of Unilateral Environmental Policies
This paper builds a two-country, two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good generates more or less emissions depending on its relative use of a clean and a dirty input. I show that a unilateral policy combining clean research subsidies and a...

Ghost-house busters: the electoral response to a large anti–tax evasion program
The incentives of political agents to enforce tax collection are key determinants of the levels of compliance. We study the electoral response to the Ghost Buildings program, a nationwide anti tax evasion policy in Italy that used innovative monitoring technologies to target buildings hidden from tax authorities. The program induced monetary and non-monetary benefits for non-evaders...

A quantitative analysis of subsidy competition in the U.S.
What motivates regional governments to subsidize firm relocations and what are the implications of the subsidy competition among them? In this paper, I address these questions using a quantitative economic geography model which I calibrate to U.S. states. I show that states have strong incentives to subsidize firm relocations in order to gain at the expense of other states. I also...

Expectations as reference points: field evidence from professional soccer
We show that professional soccer players and their coaches exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that players breach the rules of the game, measured by the referee's assignment of cards, signifcantly more often if their teams are behind the expected match...

The shadow cost of repos and bank liability structure
Making use of a structural model that allows for optimal liquidity management, we study the role that repos play in a bank's financing structure. In our model the bank's assets consist of illiquid loans and liquid reserves and are financed by a combination of repos, long--term debt, deposits and equity. Repos are a cheap source of funding, but they are subject to an...

Yet, despite numerous recent public and private initiatives to develop capacities for agricultural innovation, such in itiatives are often not well aligned with national efforts...

Corporate governance in a risk society
Under conditions of growing interconnected- ness of the global economy, more and more stakeholders are exposed to risks and costs resulting from business activities that are neither regulated nor compensated for by means of national governance. The changing distribution of risks poses a threat to the legitimacy of business firms that normally derive their legitimacy from operating in...
