Nonlinearity in Deviations From Uncovered Interest Parity: An Explanation of the Forward Bias Puzzle
Description: We provide empirical evidence that deviations from uncovered interest rate parity (UIP) display significant nonlinearities, consistent with theories based on transaction costs or limits to speculation. This evidence suggests that the forward bias documented in the literature may be less indicative of major market inefficiencies than previously thought. Monte Carlo experiments allow us to reconcile these results with the large empirical literature on the forward bias puzzle since we show that, if the true process of UIP deviations were of the nonlinear form we consider, estimation of conventional spot-forward regressions would generate the anomalies documented in previous research.

Determinants of Emigrant Deposits in Cape Verde
Description: In the last decade Cape Verde has experienced a strong accumulation of emigrant deposits. These deposits have provided much needed foreign exchange to the country, adding support to the exchange rate peg. This paper studies the long-run determinants of emigrant deposits with respect to risk, wealth, and return variables, isolating speculative and altruistic motives underlying the accumulation of flows. The study suggests that the temporary character of recent emigration is responsible for the rise in the share of flows driven by altruism. Finally, the paper discusses policy implications in light of the empirical findings and the recent literature on this topic.

The Lender of Last Resort in the European Single Financial Market
Description: This paper examines challenges in effectively implementing the lender-of-last-resort function in the EU single financial market. Briefly highlighted are features of the EU financial landscape that could increase EU systemic financial risk. Briefly described are the complexities of the EU's financialstability architecture for preventing and resolving financial problems, including lender-of-last-resort operations. The paper examines how the lender-of-last-resort function might materialize during a systemic financial disturbance affecting more than one EU member state. The paper identifies challenges and possible ways of enhancing the effectiveness of the existing architecture.

Regional Convergence in Latin America
Description: This paper presents empirical evidence on convergence of per capita output for regions within six large middle-income Latin American countries: Argentina, Brazil, Chile, Colombia, Mexico, and Peru. It explores the role played by several exogenous sectoral shocks and differences in steady states within each country. It finds that poor and rich regions within each country converged at very low rates over the past three decades. It also finds evidence of regional "convergence clubs" within Brazil and Peru- the estimated speeds of convergence for these countries more than double after controlling for different subnational levels of steady state. For the latter countries and Chile, convergence is also higher after controlling for sector-specific shocks. Finally, results show that national disparities in per capita output increased temporarily after each country pursued trade liberalization.

Can Budget Institutions Counteract Political Indiscipline?
Description: The budget is an expression of political rather than economic priorities. We confirm this proposition for a group of new and potential members of the European Union, finding that politics dominates. The contemporary practice of democracy can increase budget deficits through not only ideological preferences but also more fragmented government coalitions and higher voter participation. Long-term structural forces, triggered by societal divisions and representative electoral rules, have more ambiguous implications but also appear to increase budget pressures, as others have also found. However, our most robust, and hopeful, finding is that budget institutions-mechanisms and rules of the budget process-that create checks and balances have significant value even when the politics is representative but undisciplined, and when long-term structural forces are unfavorable.

Public Debt, Money Supply, and Inflation: A Cross-Country Study and Its Application to Jamaica
Description: This paper provides comprehensive empirical evidence that supports the predictions of Sargent and Wallace's (1981) "unpleasant monetarist arithmetic" that an increase in public debt is typically inflationary in countries with large public debt. Drawing on an extensive panel dataset, we find that the relationship holds strongly in indebted developing countries, weakly in other developing countries, but generally not in developed economies. These results are robust to the inclusion of other variables, corrections for endogeneity biases, and relaxation of common-slope restrictions and are invariant over sub-sample periods. We estimate a VAR to trace out the transmission channel and find the impulse responses consistent with the predictions of a forward-looking model of inflation. Wealth effects of public debt could also affect inflation, as posited by the fiscal theory of the price level, but we do not find supportive evidence. The results suggest that the risk of a debt-inflation trap is significant in highly indebted countries, and pure money-based stabilization is unlikely to be effective over the medium term. Our findings stress the importance of institutional and structural factors in the link between fiscal policy and inflation.

Fiscal Discipline and Exchange Rate Regimes: Evidence From the Caribbean
Description: This paper assesses the nature of fiscal discipline under alternative exchange rate regimes. First, it shows in a simple theoretical framework that fiscal agencies under a currency union with a fixed exchange rate can have the largest incentive to overspend or "free-ride" (compared to those under other exchange rate regimes) owing to their ability to spread the costs of overspending in terms of the inflation tax across both time-given the fixed exchange rate-and space-given the currency union. In contrast, such free-riding behavior does not arise under flexible regimes owing to the immediate inflationary impact of spending. Next, empirically, it shows that fiscal stances in countries with fixed pegs and currency unions regime demonstrate greater free-riding behavior than countries with more flexible regimes in 15 Caribbean countries during 1983-2004.

A Superior Hybrid Cash-Flow Taxon Corporations
Description: This paper proposes a new hybrid cash-flow tax on corporations that, on one hand, taxes only excess corporate profits as they accrue, and, on the other hand, treats real and financial transactions neutrally. It is, therefore, a superior tax compared to the cash-flow tax on real transactions that seems to have gained common acceptance. The hybrid tax is a modified version of the cash-flow tax on real and financial transactions combined. The modification involves replacing expensing of fixed assets with normal depreciation allowances, but the undepreciated value of fixed assets is carried forward with interest at the opportunity cost of equity capital.

Excess Liquidity and Effectiveness of Monetary Policy: Evidence from Sub-Saharan Africa
Description: This paper examines the pattern of excess liquidity in sub-Saharan Africa and its consequences for the effectiveness of monetary policy. The paper argues that understanding the consequences of excess liquidity requires quantifying the extent to which commercial bank holdings of excess liquidity exceed levels required for precautionary purposes. It proposes a methodology for measuring this quantity and uses it to estimate a nonlinear structural VAR model for the CEMAC region, Nigeria and Uganda. The study suggests that excess liquidity weakens the monetary policy transmission mechanism and thus the ability of monetary authorities to influence demand conditions in the economy.

Fiscal Policy and Interest Rates: How Sustainable Is The “New Economy”?
Description: This paper explores the determinants of long-term government bond yields in the Group of Seven (G-7) economies and analyzes the factors that could explain the conundrum of very low rates in the face of a variety of adverse factors in recent years. In particular, the paper focuses on the deteriorating fiscal position in the G-7 economies and enquires which factors could have offset their impact on long-term interest rates, and how sustainable they are likely to be. A model of interest rate determination is elaborated and estimated for the G-7, with explicit emphasis on capital flows and public savings. The results suggest a high likelihood of a substantial impact of the weaker budgetary positions in the G-7 on global interest rates when the offsetting unprecedented capital flows slow down.
