This paper asks whether immigration to Britain has had any impact on average wages. There seems to be a broad consensus among academics that the share of immigrants in the workforce has little or no effect on the pay rates of the indigenous population. But the studies in the literature have...

Why is GDP so much more volatile in poor countries than in rich ones? To answer this question, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. As in endogenous growth models,...

We study a small open economy characterized by two empirically important frictions— incomplete financial markets and an inability of the government to commit to policy. We characterize the best sustainable fiscal policy and show that it can amplify and prolong shocks to output. In particular,...

The enormous growth in both Social Security and private pension plans has stimulated much interest in the impact of these retirement programs on individual saving behavior and the level of national saving. The first issue is the extent to which employees covered by pension plans reduce their own...

This paper looks at the implications of heterogeneous beliefs for inflation dynamics. Following a monetary policy shock, inflation peaks after output, is inertial, and can be characterized by a Hybrid Phillips Curve. It presents a novel channel through which systematic monetary policy can affect...

The success in marketing original issue high-yield bonds has generated significant interest in their default experience. Studies comparing defaults to the par value of outstanding issues such as Altman (1987), Altman and Nammacher (1985), and Weinstein (1987) have found relatively low default...

Evidence of an operative credit channel has been inconclusive. The inability to clearly distinguish the effects of shocks to loan supply from those to loan demand has made it difficult to quantify the importance of this transmission mechanism to the economy. This paper provides an innovative...

We consider a neoclassical interpretation of Germany and Japan's rapid postwar growth that relies on a catch-up mechanism through capital accumulation where technology is embodied in new capital goods. Using a putty-clay model of production and investment, we are able to capture many of the key...

This paper addresses the proper measurement of financial service output that is not priced explicitly. It shows how to impute nominal service output from financial intermediaries’ interest income and how to construct price indices for those financial services. We present an optimizing model...

Within optimal investment programs, the accumulation of capital is a stable function of marginal q. Much of the interest in q, however, derives from its potential to reflect the demand for capital when the optimal program changes. If the marginal return on capital diminishes as capital...
