Although many studies in macroeconomics have examined the role of insurance in the presence of income risk, whether aggregate shocks are insurable has not been sufficiently investigated. We present a simple two-period general equilibrium model to show the conditions under which insurance against...

We propose a framework for institutional change in the 'rules-in-equilibrium' tradition and introduce the term institutional incompleteness. Institutions are incomplete when their constituent rules fail to induce behavioural beliefs about the strategies of others and hence fail to achieve an...

We examine the role of government investment in defense capital as a deterrence tool. Using an optimal fiscal policy framework with endogenous disaster risk, we allow for an endogenous determination of geopolitical risk and defense capacity, which we discipline using the Geopolitical Risk Index....

We argue that capital misallocation arises endogenously due to incomplete consumption insurance. We model risk-averse entrepreneurs with heterogeneous productivity who face idiosyncratic output shocks and choose how much capital to rent before uncertainty unfolds. We show that incomplete markets...

Change ownership reforms for electric cooperatives (ECs) have once again attracted policymakers' interest due to current e!orts in expediting their privatization. This note serves as input to this ongoing conversation using the lens of competition. We argue that unchecked consolidation -...

We study the effects of movements in aggregate lending standards on macroeconomic aggregates and inequality. We show in a New Keynesian model with heterogeneous households and housing that a looser loan-to-value (LTV) ratio stimulates housing demand, nondurable consumption, and output. Our model...

I study the transmission mechanism of Quantitative Easing (QE) in the form of large-scale asset purchases in the mortgage market to aggregate consumption. To this end, I develop a New Keynesian model that features heterogeneous households, a microfounded housing market, and frictional...

During the Covid-19 crisis, most OECD countries used short-time work (subsidized reductions in working hours) to preserve employment. This paper documents that short-time work affects the behavior of firms (supply) and households (demand). First, using household survey data from Germany, we show...

Prepaid electricity contracts lower enforcement costs but may burden consumers, particularly when market frictions are present. This paper presents the results of a randomized control trial where 2,000 randomly selected, rural Rwandese consumers were offered a line of credit for electricity...

This paper demonstrates that perfectly calibrating a multi-asset model to observed market prices of all basket call options is insufficient to uniquely determine the price of a best-of call option. Previous research on multi-asset option pricing has primarily focused on complete market settings...

We explore to what extent real returns on investment portfolios can be hedged against inflation risk by using existing financial market instruments. We find that inflation-linked bonds offer only limited protection against inflation risk and that nominal debt and stocks play at least comparable...
