We estimate a panel VAR model that captures cross-country, dynamic interlinkages for 10 euro area countries using quarterly data for the period 1999-2016. Our analysis suggests that fiscal spillovers are significant and tend to be larger for countries with close trade and financial links as well, as for fiscal shocks originating from larger countries. The current account appears to be the main channel of transmission, although strong trade integration among countries in the euro area and spillback effects tend to zero-out the net trade impact in some cases. A subsample analysis shows that the effects of fiscal policy have changed over time, with larger estimated domestic multipliers and spillovers between 2011 and 2014.
This paper develops a structural macroeconometric model of the world economy,
disaggregated into forty national economies, to facilitate multilaterally consistent
macrofinancial policy, risk and spillover analysis. This panel dynamic stochastic general
equilibrium model features a range of nominal and real rigidities, extensive
macrofinancial linkages, and diverse spillover transmission channels. These
macrofinancial linkages encompass bank and capital market based financial
intermediation, with financial accelerator mechanisms linked to the values of the housing
and physical capital stocks. A variety of monetary policy analysis, fiscal policy analysis,
macroprudential policy analysis, spillover analysis, and forecasting applications of the
estimated model are demonstrated. These include quantifying the monetary, fiscal and
macroprudential transmission mechanisms, accounting for business cycle fluctuations, and
generating relatively accurate forecasts of inflation and output growth.
Do growth spells in Africa end because of bad realizations of the same factors that influence growth spells in the rest of the world, or because of different factors altogether? To answer this question, we examine determinants of growth spells in Africa and the rest of the world using Bayesian Mode Averaging techniques for proportional hazards models. We define growth spells as periods of sustained growth episodes between growth accelerations and decelerations and then relate the probability that a growth spell ends to various determinants including exogenous shocks, physical and human capital, macroeconomic policy, and sociopolitical factors. Our analysis suggests that determinants of growth spells in Africa are different from those in the rest of the world. The majority of the identified robust determinants have a distinct impact in only one of the two samples: initial income, terms of trade, exchange rate undervaluation and inflation, influence spells only in the world sample, while openness and droughts seem to only affect Africa. In addition, a few common determinants - proxies for human and physical capital and changes in the world interest rate - have very different marginal effects in the two samples.

We document that the U.S. dollar exchange rate drives global trade prices and volumes. Using a
newly constructed data set of bilateral price and volume indices for more than 2,500 country
pairs, we establish the following facts: 1) The dollar exchange rate quantitatively dominates the
bilateral exchange rate in price pass-through and trade elasticity regressions. U.S. monetary
policy induced dollar fluctuations have high pass-through into bilateral import prices. 2) Bilateral
non-commodities terms of trade are essentially uncorrelated with bilateral exchange rates.
3) The strength of the U.S. dollar is a key predictor of rest-of-world aggregate trade volume and
consumer/producer price inflation. A 1 percent U.S. dollar appreciation against all other
currencies in the world predicts a 0.6–0.8 percent decline within a year in the volume of total
trade between countries in the rest of the world, controlling for the global business cycle. 4)
Using a novel Bayesian semiparametric hierarchical panel data model, we estimate that the
importing country’s share of imports invoiced in dollars explains 15 percent of the variance of
dollar pass-through/elasticity across country pairs. Our findings strongly support the dominant
currency paradigm as opposed to the traditional Mundell-Fleming pricing paradigms.
This paper develops a structural macroeconometric model of the world economy, disaggregated into thirty five national economies. This panel unobserved components model features a monetary transmission mechanism, a fiscal transmission mechanism, and extensive macrofinancial linkages, both within and across economies. A variety of monetary policy analysis, fiscal policy analysis, spillover analysis, and forecasting applications of the estimated model are demonstrated, based on a Bayesian framework for conditioning on judgment.

This paper investigates the channels through which remittances affect macroeconomic volatility in African countries using a dynamic stochastic general equilibrium (DSGE) model augmented with financial frictions. Empirical results indicate that remittances—as a share of GDP—have a significant smoothing impact on output volatility but their impact on consumption volatility is somewhat small. Furthermore, remittances are found to absorb a substantial amount of GDP shocks in these countries. An investigation of the theoretical channels shows that the stabilization impact of remittances essentially hinges on two channels: (i) the size of the negative wealth effect on labor supply induced by remittances and, (ii) the strength of financial frictions and the ability of remittances to alleviate these frictions.
This paper investigates financial frictions in US postwar data to understand the interaction between the real business cycle and the credit market. A Bayesian estimation technique is used to estimate a large Vector Autoregression and New Keynesian models demonstrating how financial shocks can have a large and sluggish impact on the economy. I identify the default risk and the maturity mismatch channels of monetary policy transmission; I further employ a generalized-IRF to establish countercyclicality of risk spreads; and I show that the maturity mismatch shocks produce a stronger impact than the default risk shocks.
This paper attempts to identify robust patterns of cross-country growth behavior in the world as a whole and Africa. It employs a novel methodology that incorporates a dynamic panel estimator, and Bayesian Model Averaging to explicitly account for model uncertainty. The findings indicate that: (i) in addition to initial conditions, various economic factors such as higher investment, lower inflation, lower government consumption, better fiscal stance, improved political environment, exogenous terms-of-trade shocks, and fixed geographical factors are robustly correlated with growth; (ii) what is good for growth around the world is, in principle, also good for growth in Africa; and (iii) political and institutional variables are particularly important in explaining African growth.
