Working Paper
Tax Progressivity, Economic Booms, and Trickle-Up Economics
We propose a method to decompose changes in the tax structure into a component measuring the level of taxes and a component orthogonal to the level that measures progressivity. While our focus is on the progessivity results, we find that the level shock is similar to standard tax shocks found in the empirical literature in that a rise in the level is contractionary. An increase in tax progressivity sets off an economic boom. Those at the bottom of the income distribution (who are constrained hand-to-mouth consumers) set off a consumption boom that expands the overall economy. Those at the top ...

Commodity Exports, Financial Frictions and International Spillovers
This paper offers a solution to the international co-movement puzzle found in open-economy macroeconomic models. We develop a small open-economy (SOE) dynamic stochastic general equilibrium (DSGE) model describing three endogenous channels that capture spillovers from the world to a commodity exporter: a world commodity price channel, a domestic commodity supply channel and a financial channel. We estimate our model with Bayesian methods on two commodity-exporting SOEs, namely Canada and South Africa. In addition to explaining international business cycle synchronization, the new model ...

Sudden Stops and COVID-19: Lessons from Mexico’s History
The COVID-19 pandemic produced a sharp contraction in capital flows in emerging markets during the spring of 2020. Such contractions are known as “sudden stops” and historically have been associated with significant downturns in a country’s economic activity. Evidence from Mexico’s financial crisis history suggests that sudden stops tend to exhibit a common pattern: the crisis lasts one to two years before a rapid but partial recovery, followed by years of protracted stagnation.

Forecasting the effects of reduced defense spending
Forecasts from a vector autoregressive model indicate that the substantial cuts in defense spending proposed by the Bush Administration in 1991 are likely to reduce GNP in both the short run and the long run. These forecasts hold even if proceeds from the spending cuts are used to reduce the federal debt. The long-range VAR forecasts, in particular, contrast markedly with those of the large-scale econometric models employed by the Congressional Budget Office.
Could More Progressive Taxes Increase Income Inequality?
One paper posits that making taxes more progressive could boost lower-income households initially, but more money would eventually float to those with higher incomes.

Capital controls or exchange rate policy? a pecuniary externality perspective
In the aftermath of the global nancial crisis, a new policy paradigm has emerged> in which old-fashioned policies such as capital controls and other government distor-> tions have become part of the standard policy toolkit (the so-called macro-prudential> policies). On the wave of this seemingly unanimous policy consensus, a new strand> of theoretical literature contends that capital controls are welfare enhancing and can> be justi ed rigorously because of second-best considerations. Within the same the-> oretical framework adopted in this fast-growing literature, we show that a credible> ...

Optimal Policy for Macro-Financial Stability
There is a new and now large literature analyzing government policies for financial stability based on models with endogenous borrowing constraints. These normative analyses build upon the concept of constrained efficient allocation, where the social planner is constrained by the same borrowing limit that agents face. In this paper, we show that the same set of policy tools that implement the constrained efficient allocation can be used by a Ramsey planner to replicate the unconstrained allocation, thus achieving higher welfare. The constrained social planner approach may lead to inaccurate ...

Regionalization vs. globalization
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. Our model allows us to assess the roles played by the global, regional, and country-specific factors in explaining business cycles in a large sample of countries and regions over the period 1960?2010. We find that, since the mid-1980s, the importance of regional factors has increased markedly in explaining business cycles especially in regions that ...

Tax Progressivity, Economic Booms, and Trickle-Up Economics
We propose a method to decompose changes in the tax structure into orthogonal components measuring the level and progressivity of taxes. While our focus is on the progessivity results, we find that the level shock is similar to standard tax shocks found in the empirical literature in that a rise in the level is contractionary. We find that an increase in tax progressivity sets off an economic boom. When tax progressivity increases, those at the bottom of the income distribution experience an increase in disposable income; these consumers have a high marginal propensity to consume, and this ...
