This paper presents a simple Ramsey-type model example where two infinitely-living agents have same utility function except for time preference, and shows that equilibrium is indeterminate that is to be interpreted as being non-existent. The issues regarding New Keynesian transversality...

This paper characterizes the optimal inflation buffer consistent with a zero lower bound on nominal interest rates in a New Keynesian sticky-price model. It is shown that a purely forward-looking version of the model that abstracts from inflation inertia would significantly underestimate the...

This paper considers the extent to which expenditure by contestants inimperfectly discriminating rent-seeking contests dissipates all or only partof the rent. In particular, we investigate strategic effects, technologicaleffects and asymmetry under an assumption of diminishing returns to...

Life insurers typically grant policyholders a surrender option. We demonstrate that the resulting lapse risk could materialise in the form of a "policyholder run" if interest rates were to increase sharply. An inverse stress test based on a unique set of regulatory panel data suggests that...

Die EU hat durch die Zinsenrichtlinie einerseits eindeutig von einer Politik, die auf einem Vertrauen gegenüber dem Bürger und einer gewissen Selbstbestimmung beruhte, zu einer Vorgehensweise gewechselt die durch Misstrauen und Kontrolle geprägt ist. Andererseits erscheinen die Regelungen der...

The life insurance sector is exposed to systematic liquidity risk, because policyholders would have a common incentive to surrender their policies in the event of a severe macroeconomic shock. Life insurers would, then, have to sell assets, and these fire sales would amplify the original shock....

I develop a model in which a duopoly of credit rating agencies endogenously use issuers as messengers to find out each other's assessments before offering ratings. Information flows between rating agencies when (i) rating agencies' incentives are aligned due to both of their ratings being...

Life insurers typically grant policyholders a surrender option. We demonstrate that the resulting lapse risk could materialise in the form of a "policyholder run" if interest rates were to increase sharply. An inverse stress test based on a unique set of regulatory panel data suggests that...

This paper considers a model of a rating agency with multiple clients, in which each client has a separate market that forms a belief about the quality of the client after the agency issues a rating. When the clients are rated separately (individual rating), the credibility of a good rating in...

We explore the economics and optimal design of "permissioned" distributed ledger technology (DLT) in a credit economy. Designated validators verify transactions and update the ledger at a cost that is derived from a supermajority voting rule, thus giving rise to a public good provision game....
