We use a general equilibrium finance model that features explicit government purchases
of private debts to shed light on some of the principal working mechanisms of the Federal
Reserve’s large-scale asset purchases (LSAP) and their macroeconomic effects.
We develop a theory of labor quality based on (i) the division of the labor force
between unskilled and skilled workers and (ii) investments in skilled workers. In our
theory, countries differ in two key dimensions: talent and total factor productivity
This paper deals with a classic development question: how can the process of economic
development – transition from stagnation in a traditional technology to industrialization
and prosperity with a modern technology – be accelerated?
This paper determines the most appropriate ways to model diffusion and jump features of exchange
rates. Simulations show that intraday periodicity in volatility prevents conventional tests from accurately
identifying the frequency and location of jumps.
This paper uses several methods to study the interrelationship among Divisia monetary aggregates, prices, and income, allowing for nonstationary, nonlinearities, asymmetries, and time-varying relationships among the series.
Policymakers often use measures of tax incidence (generational accounts) as criteria for policy selection. We use a quantitative model of optimal intergenerational policy to evaluate the ability of the tax incidence metric to capture the identity of recipients and contributors and the magnitudes transferred.
Most empirical studies based on U.S. data suggest that the fiscal multiplier is less
than 1 (e.g., Barro and Redlick, 2011). However, Keynes argued that the multiplier
would be the largest when markets have failed to the greatest extent in coordinating
economic activities (such as during the Great Depression with rampant unemployment
and low capacity utilization).
We construct a model to capture the Keynesian idea that production and employment
decisions are based on expectations of aggregate demand driven by sentiments and
that realized demand follows from the production and employment decisions of firms.
We present a thought-provoking study of two monetary models: the cash-in-advance and
the Lagos and Wright (2005) models. We report that the different approach to modeling
money—reduced-form vs. explicit role—neither induces fundamental theoretical nor quantitative
differences in results.
On May 29, 2008, the Wall Street Journal reported that several large international banks were reporting unjustifiably low LIBOR rates. Since then two large banks, Barclays and UBS, have paid significant fines for manipulating their LIBOR rates, and additional banks are expected to be fined.
Both global and regional economic linkages have strengthened substantially over the
past quarter century. We employ a dynamic factor model to analyze the implications of these
linkages for the evolution of global and regional business cycles.
This paper provides a general framework for the quantitative analysis of
stochastic dynamic models. We review convergence properties of some
numerical algorithms and available methods to bound approximation errors.
