Effects of government investment are studied in an estimated neoclassical growth model. The analysis focuses on two dimensions that are critical for understanding government investment as a fiscal stimulus: implementation delays for building public capital and expected fiscal adjustments to deficit-financed spending. Implementation delays can produce small or even negative labor and output responses to increases in government investment in the short run. Anticipated fiscal adjustments matter both quantitatively and qualitatively for long-run growth effects. When public capital is insufficiently productive, distorting financing can make government investment contractionary at longer horizons.
Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax mobilization problems. This paper develops a dynamic stochastic model to analyze the macroeconomic effects of investing resource revenues, making explicit the role of public investment inefficiency, absorptive capacity constraints, Dutch disease, and financing needs to sustain capital. Revenue exhaustibility raises medium-term issues of how to sustain capital built during a windfall, while revenue volatility raises short-term concerns about macroeconomic instability. Using the model, country applications show how combining public investment with a resource fund-a sustainable investing approach-can address the problems associated with exhaustibility and n
News—or foresight—about future economic fundamentals can create rational expectations equilibria with non‐fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example of foresight, simple theory makes transparent the economic behavior and information structures that generate non‐fundamental equilibria. Econometric analyses that fail to model foresight will obtain biased estimates of output multipliers for taxes; biases are quantitatively important when two canonical theoretical models are taken as data generating processes. Both the nature of equilibria and the inferences about the effects of anticipated tax changes hinge critically on hypothesized information flows. Different methods for extracting or hypothesizing the information flows are discussed and shown to be alternative techniques for resolving a non‐uniqueness problem endemic to moving average representations.
Abstract. Fiscal foresight-the phenomenon that legislative and implementation lags ensure that private agents receive clear signals about the tax rates they face in the future-is intrinsic to the tax policy process. This paper develops an analytical framework to study the econometric implications of fiscal foresight. Simple theoretical examples show that foresight produces equilibrium time series with a non-invertible moving average component, which misaligns the agents' and the econometrician's information sets in estimated VARs. Economically meaningful shocks to taxes, therefore, cannot be extracted from statistical innovations in conventional ways. Econometric analyses that fail to align agents' and the econometrician's information sets can produce distorted inferences about the effects of tax policies. Because non-invertibility arises as a natural outgrowth of the fact that agents' optimal decisions discount future tax obligations, it is likely to be endemic to the study of fiscal policy. In light of the implications of the analytical framework, we evaluate two existing empirical approaches to quantifying the impacts of fiscal foresight. The paper also offers a formal interpretation of the narrative approach to identifying fiscal policy.
This paper contributes to the debate about fiscal multipliers by studying the impacts of government investment in conventional neoclassical growth models. The analysis focuses on two dimensions of fiscal policy that are critical for understanding the effects of government investment: implementation delays associated with building public capital projects and expected future fiscal adjustments to debt-financed spending. Implementation delays can produce small or even negative labor and output responses in the short run; anticipated fiscal financing adjustments matter both quantitatively and qualitatively for long-run growth effects. Taken together, these two dimensions have important implications for the short-run and long-run impacts of fiscal stimulus in the form of higher government infrastructure investment. The analysis is conducted in several models with features relevant for studying government spending, including utility-yielding government consumption, time-to-build for private investment, and government production.
