When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects network clearing). We show that those frictions and the...

We examine the allocation of scarce attention in team production. Each team member is in charge of a specialized task, which must be adapted to a privately observed shock and coordinated with other tasks. Coordination requires that agents pay attention to each other, but attention is in limited...

The fall in US macroeconomic volatility from the mid-1980s coincided with a strong rise in asset prices. Recently, this rise, and the crash that followed, have been attributed to overconfidence in a benign macroeconomic environment of low volatility. This paper introduces learning about the...

We investigate the role of information spillovers (IS) in determining firms' labour adjustments. We test the proposition that information on relevant state variables spills over through one firm's decision to affect those of other firms. Our test is based on the assumption that spillovers matter...

I develop a model of (individually rational) collective reality denial in groups, organizations and markets. Whether participants' tendencies toward wishful thinking reinforce or dampen each other is shown to hinge on a simple and novel mechanism. When an agent can expect to benefit from other's...

We demonstrate how endogenous information acquisition in credit markets creates lending cycles when competing banks undertake their screening decisions in an uncoordinated way, thereby highlighting the role of intertemporal screening externalities induced by lending market competition as a...

This paper develops a dynamic stochastic general equilibrium model with rational inattention. Households and decision-makers in firms have limited attention and decide how to allocate their attention. The paper studies the implications of rational inattention for business cycle dynamics. Impulse...

Economic decisions such as occupational and entrepreneurial choices may violate true comparative advantage when economic agents are uncertain about which activity best matches their talents. If relative performance varies over the business cycle (for instance, if downturns affect...

Expectations play a central role in modern macroeconomics. The econometric learning approach, in line with the cognitive consistency principle, models agents as forming expectations by estimating and updating subjective forecasting models in real time. This approach provides a stability test for...

Under rational expectations monetary policy is generally highly effective in stabilizing the economy. Aggregate demand management operates through the expectations hypothesis of the term structure --- anticipated movements in future short-term interest rates control current demand. This paper...
