"We quantify the role of financial frictions and the initial misallocation of resources in explaining development dynamics. Following a reform that triggers efficient reallocation of resources, our model economy with financial frictions converges slowly to the new steady state-it takes twice as long to cover half the distance to the steady state as the neoclassical growth model. Investment rates and total factor productivity start out low and rise over time. These model dynamics are endogenously determined by the extent of initial resource misallocation and the degree of financial frictions. We present data from post-war miracle economies on the evolution of macro aggregates, factor reallocation, and establishment size distribution, which support the aggregate and micro-level implications of our theory"--National Bureau of Economic Research web site

Abstract
Which firms are more sensitive to an aggregate financial shock? What can be learnt from these heterogeneous responses? We evaluate and answer these questions from both empirical and theoretical perspectives. Using microdata from Portugal during the sovereign debt crisis we find that highly leveraged firms and firms with a larger share of short-term debt on their balance sheets contracted more in the aftermath of the financial shock. We analyse the conditions under which leverage and debt maturity determine the sensitivity of firms' investment decisions to financial shocks in standard models of investment under financial frictions. In doing so, we extend these models to feature a maturity choice. We show that simple versions of these models are not consistent with the observed heterogeneous responses. The model needs the presence of frictions when issuing long-term debt to rationalise the empirical findings.

We study a model with heterogeneous producers that face collateral and cash in advance constraints. These two frictions give rise to a non-trivial financial market in a monetary economy. A tightening of the collateral constraint results in a credit-crunch generated recession. The model can suitable be used to study the effects on the main macroeconomic variables - and on welfare of each individual - of alternative monetary - and fiscal - policies following the credit crunch. The model reproduces several features of the recent financial crisis, like the persistent negative real interest rates, the prolonged period at the zero bound for the nominal interest rate, the collapse in investment and low inflation, in spite of the very large increases of liquidity adopted by the government. The policy implications are in sharp contrast with the prevalent view in most Central Banks, based on the New Keynesian explanation of the liquidity trap.

This paper analyzes the role of specialized high-skilled labor in the disproportionate growth of the service sector. Empirically, the importance of skill-intensive services has risen during a period of increasing relative wages and quantities of high-skilled labor. We develop a theory in which demand shifts toward more skill-intensive output as productivity rises, increasing the importance of market services relative to home production. Consistent with the data, the theory predicts a rising level of skill, skill premium, and relative price of services that is linked to this skill premium. (JEL J24, L80, L90)
