Most individual life insurance policies lapse, with lapsers cross-subsidizing non-lapsers. We show that and lapse patterns predicted by standard rational expectations models are the opposite of those observed empirically. propose two behavioral consistent evidence: (i) consumers forget to pay premiums (ii) understate future liquidity needs. conduct surveys a large insurer. New buyers believe th...

The social cost of carbon is the expected present value damages from emitting one ton today. We use perturbation theory to derive an approximate tractable expression for this adjusted climatic and economic risk. allow different aversion risk intertemporal fluctuations, skewness dynamics in distributions climate sensitivity damage ratio, correlated shocks. identify prudence, insurance, exposure ...

A popular solution to the looming entitlements crisis in the United States is to increase the eligibility age for Medicare. Using an empirical model of insurance choice with endogenous prices, I find that this would have a modest welfare cost. The losses are concentrated among those who lose Medicare coverage. For the non-elderly, the benefit of lower taxes is mitigated by a higher price for me...

We develop a random-matching model to study the price dynamics of monies produced privately according time-consuming mining technology. For our leading example, there exists unique equilibrium where value money increases over time and reaches steady state. There is also continuum perfect-foresight equilibria inflates bursts gradually time. Initially, held for speculative motive, but it acquires...

We develop a multisector sticky-price DSGE model that can endogenously deliver differential responses of prices to aggregate and sectoral shocks. Input-output production linkages (standard) monetary policy rule contribute slow response In turn, labor market segmentation at the level induces within-sector strategic substitutability in price-setting decisions, which helps fast sector-specific est...

In this paper we develop the first search-theoretic monetary model of a two-country global economy. We show the connection between deep monetary frictions (i.e. search and matching frictions), capital holdup externalities, and the realization of an endogenous departure from the “excess smoothness” problem in the real exchange rate found in standard models. Using this alternative monetary model,...

We estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on United Kingdom data. Our estimates suggest that price stickiness is a more important source of nominal rigidity in the U.K. than wage stickiness. Our estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects govern...

This paper assesses the presence and importance of neo-Fisher effect in postwar data. It formulates estimates an empirical a New Keynesian model driven by stationary nonstationary monetary real shocks. In accordance with conventional wisdom, temporary increases nominal interest rate are estimated to cause decreases inflation output. The main finding is that permanent shocks increase long run ra...
