This paper studies the effects of the introduction of unemployment compensation (UC) in countries characterized by pervasive informality. We provide a simple framework to analyze the impact of UC on the allocation of workers between formal and informal activities, as well as the allocation of workers between sectors featuring different incentives to go informal. We show that a reasonable amount of UC may reduce informality, while larger amounts of UC induce large disincentives to go formal because of the level of taxation involved. We also argue that the financing of UC should be part and parcel of a well‐conceived UC system. We show that UC finance based on payroll taxes is likely to entail an excess level of informality resulting from cross‐subsidies between heterogenous sectors. The introduction of a simple layoff tax meant to finance the UC system is then shown to reduce informality, hence highlighting how a well‐designed financing scheme may be used as a supplementary instrument to curb informality.  相似文献

Most central banks perceive a trade‐off between stabilizing inflation and stabilizing the gap between output and desired output. However, the standard new Keynesian framework implies no such trade‐off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare‐relevant output gap. In this paper, we argue that this property of the new Keynesian framework, which we call the divine coincidence, is due to a special feature of the model: the absence of nontrivial real imperfections. We focus on one such real imperfection, namely, real wage rigidities. When the baseline new Keynesian model is extended to allow for real wage rigidities, the divine coincidence disappears, and central banks indeed face a trade‐off between stabilizing inflation and stabilizing the welfare‐relevant output gap. We show that not only does the extended model have more realistic normative implications, but it also has appealing positive properties. In particular, it provides a natural interpretation for the dynamic inflation–unemployment relation found in the data.  相似文献

“Limits of Arbitrage” theories hypothesize that the marginal investor in a particular asset market is a specialized arbitrageur rather than a diversified representative investor. We examine the mortgage‐backed securities (MBS) market in this light. We show that the risk of homeowner prepayment, which is a wash in the aggregate, is priced in the MBS market. The covariance of prepayment risk with aggregate wealth implies the wrong sign to match the observed prices of prepayment risk. The price of risk is better explained by a kernel based on MBS market‐wide specific risk, consistent with the specialized arbitrageur hypothesis.  相似文献

In this paper, I estimate the magnitude of an informational friction limiting credit reallocation to firms during the 2007 to 2009 financial crisis. Because lenders rely on private information when deciding which relationship to end, borrowers looking for a new lender are adversely selected. I show how to separately identify private information from information common to all lenders but unobservable to the econometrician by using bank shocks within a discrete choice model of relationships. Quantitatively, these informational frictions appear to be too small to explain the credit crunch in the U.S. syndicated corporate loan market.  相似文献

An action is robustly rationalizable if it is rationalizable for every type who has almost common certainty of payoffs. We illustrate by means of an example that an action may not be robustly rationalizable even if it is weakly dominant, and argue that robust rationalizability is a very stringent refinement of rationalizability. Nonetheless, we show that every strictly rationalizable action is robustly rationalizable. We also investigate how permissive robust rationalizability becomes if we require that players be fully certain of their own payoffs.  相似文献

On November 14–15, 2008, the Federal Reserve Bank of Cleveland hosted a conference on “Liquidity in frictional asset markets.” In this paper, we review the literature on asset markets with trading frictions in both finance and monetary theory using a simple search‐theoretic model, and we discuss the papers presented at the conference in the context of this literature. We will show the diversity of topics covered in this literature, for example, the dynamics of housing and credit markets, the functioning of payment systems, optimal monetary policy and the cost of inflation, the role of banks, the effect of informational frictions on asset trading.  相似文献

The paper considers a repeated election game between an infinitely-lived representative voter and finitely-lived, heterogeneous politicians. The voter's prior belief about the incumbent's competency is updated during the incumbent's first term in office. The voter's problem is to find a rule that simultaneously selects and controls politicians. We show that the simple performance rule, standard in the literature, is justified as a time-consistent rule for a forward-looking voter. The outcome of a large class of perfect equilibria is "strategic caution": incumbent politicians slow down the voter's Bayesian learning by taking only weakly informative actions.  相似文献

Liquidity and Credit Risk   总被引:3,自引:0,他引:3  
We develop a structural bond valuation model to simultaneously capture liquidity and credit risk. Our model implies that renegotiation in financial distress is influenced by the illiquidity of the market for distressed debt. As default becomes more likely, the components of bond yield spreads attributable to illiquidity increase. When we consider finite maturity debt, we find decreasing and convex term structures of liquidity spreads. Using bond price data spanning 15 years, we find evidence of a positive correlation between the illiquidity and default components of yield spreads as well as support for downward‐sloping term structures of liquidity spreads.  相似文献
