Global Factors in the Term Structure of Interest Rates

This paper introduces global factors within a FAVAR framework in an empirical affine term structure model. We apply our method to a panel of international yield curves and show that global factors account for more than 80 percent of term premia in advanced economies. In particular they tend to explain long-term dynamics in yield curves, as opposed to domestic factors which are instead more relevant to short-run movements. We uncover the key role for global curvature in shaping term premia dynamics. We show that this novel factor precedes global economic and financial instability. In particular, it coincides with immediate expectations of permanent expansionary monetary policy during the recent crisis.

Does Fiscal Policy Affect Interest Rates? Evidence from a Factor-Augmented Panel

This paper reconsiders the effects of fiscal policy on long-term interest rates employing a Factor Augmented Panel (FAP) to control for the presence of common unobservable factors. We construct a real-time dataset of macroeconomic and fiscal variables for a panel of OECD countries for the period 1989-2012. We find that two global factors—the global monetary and fiscal policy stances—explain more than 60 percent of the variance in the long-term interest rates. Compared to the estimates from models which do not account for global factors, we find that the importance of domestic variables in explaining long-term interest rates is weakened. Moreover, the propagation of global fiscal shocks is larger in economies characterized by macroeconomic and institutional weaknesses.

Investment scaling up and the role of government

ABSTRACT This article studies the fiscal and welfare implications of a scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side. In our simulations, the scaling up of public investments results in higher long-run output and consumption levels but requires a fiscal stabilization package in order to preserve fiscal sustainability. The effects on consumers’ welfare after the fiscal adjustment are nontrivial. Our welfare analysis shows that consumers’ welfare is increased when the government smooths the fiscal adjustment via higher borrowing and not through an increase in taxation. Moreover, the comparison between several stabilization packages via tax adjustment shows that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption. Lower fiscal costs that do not undermine fiscal sustainability can however be achieved if the government manages to reduce inefficiency in tax collection. Finally, we consider a change in the trade regime that causes a decline in revenues. We find that the higher fiscal burden required to preserve fiscal sustainability would completely wipe out the welfare gain of higher public investments.

Investment Scaling-up and the Role of Government: the Case of Benin

This paper studies the fiscal implications for the Beninese economy of scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side. While scaling up of public investments results in higher long-run output and consumption levels, a fiscal stabilization package is required in order to preserve fiscal sustainability. A welfare analysis shows that consumers’ welfare is increased when the government smoothes the fiscal adjustment via higher borrowing. Moreover, the comparison between several stabilization packages highlights the fact that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption to materialize earlier. Lower fiscal costs can however be achieved if the government manages to reduce inefficiency in tax collection. Finally, we consider a change in the trade regime that causes a decline in revenues. We find that the higher fiscal burden required to preserve fiscal sustainability would completely wipe out the welfare gain of higher public investments.

Sub-National Government's Risk Premia: Does Fiscal Performance Matter?

This paper examines the determinants of sub-national governments risk premia using secondary market data for U.S., Canada, Australia and Germany. It finds that, as for central governments, fiscal fundamentals matter in the pricing of risk premia, and sub-national governments with higher public debt and larger deficits pay higher premia. However, this relationship is not uniform across countries. Market pricing mechanisms are less effective in presence of explicit or implicit guarantees from the central government. Specifically, we show that in pricing risk premia of sub-national governments, markets are less responsive to fiscal fundamental when sub-national governments depend on high transfers from the central government, i.e., when there is some form of implicit guarantee from the center. Using primary market data, the paper also looks at whether transfer dependency from the central government influences sub-national governments’ incentive to access markets. We show that high transfer dependency lowers the probability of sub-national governments to borrow on capital markets.

Make Investment Scaling-Up Work in Benin : A Macro-Fiscal Analysis

This paper conducts a systematic growth and fiscal analysis to determine: (1) the growth potential of Benin’s ambitious scaling-up of investment, and (2) how the government can generate the necessary fiscal space needed to increase investment without jeopardizing Benin’s solid macroeconomic performance.
