Political Monetary Cycles and a New de facto Ranking of Central Bank Independence

This paper examines the extent to which monetary policy is manipulated for political purposes by testing for the presence of political monetary cycles between 1972 and 2001. This is the first study of its kind to include not only advanced countries but also a large sample of developing nations where these cycles are more likely to exist. We estimate panel regressions of a monetary policy indicator on an election dummy and control variables. We do not find evidence of political monetary cycles in advanced countries but find strong evidence in developing nations. Based on our results, we construct a new de facto ranking of central bank independence derived from the extent to which monetary policy varies with the election cycle. Our ranking of CBI is therefore based on the behavior of central banks during election cycles when their independence is likely to be challenged or their lack of independence is likely to be revealed. The ranking also avoids well-known problems with existing measures of central bank independence.Political monetary cycles; central bank independence

The Case Against Power Utility and a Suggested Alternative: Resurrecting Exponential Utility

Utility modeled as a power function is commonly used in the literature despite the fact that it is unbounded and generates asset pricing puzzles. The unboundedness property leads to St. Petersburg paradox issues and indifference to compound gambles, but these problems have largely been ignored. The asset pricing puzzles have been solved by introducing habit formation to the usual power utility. Given these issues, we believe it is time re-examine exponential utility. Exponential utility was abandoned largely because it implies increasing relative risk aversion in a cross-section of individuals and nonstationarity of the aggregate consumption to wealth ratio, contradicting macroeconomic data. We propose an alternative preference specification with exponential utility and relative habit formation. We show that this utility function is bounded, consistent with asset pricing facts, generates near-constant relative risk aversion in a cross-section of individuals and a stationary ratio of aggregate consumption to wealth.unbounded utility, asset pricing puzzles, habit formation

Oil Crisis, Energy-Saving Technological Change and the Stock Market Crash of 1973-74

The market value of U.S. corporations was nearly halved following the oil crisis of October 1973. Real energy prices more than doubled by the end of the decade, increasing energy costs and spurring innovation in energy-saving technologies by corporations. This paper uses a neoclassical growth model to quantify the impact of the increase in energy prices on the market value of U.S. corporations. In the model, corporations adopt energy-saving technologies as a response to the energy price shock and the price of installed capital falls due to investment irreversibility. The model calibrated to match the subsequent decline in energy consumption in the U.S. generates a 24% decline in market valuation; accounting for nearly half of what is observed in the data.Stock market crash, Energy crisis, Energy saving technological change, Induced innovation

Should Central Banks of Small Open Economies Respond to Exchange Rate Fluctuations? The Case of South Africa

We estimate a New Keynesian small open economy DSGE model for South Africa, using Bayesian techniques. The model features imperfect competition, incomplete asset markets, partial exchange rate pass-through, and other commonly used nominal and real rigidities, such as sticky prices, price indexation and habit formation. We study the effects of various shocks on macroeconomic variables, and calculate the optimal Taylor rule coefficients using a loss function for the central bank. We find that the optimal Taylor rule places a heavier weight on inflation and output than the estimated Taylor rule, but almost no weight on the depreciation of currency.optimal monetary policy, small open economy, Bayesian estimation

Should monetary policy lean against housing market booms?

Should monetary policy lean against housing market booms? We approach this question using a small-scale, regime-switching New Keynesian model, where housing market crashes arrive with a logit probability that depends on the level of household debt. This crisis regime is characterized by an elevated risk premium on mortgage lending rates, and, occasionally, a binding zero lower bound on the policy rate, imposing large costs on the economy. Using our set-up, we examine the optimal level of monetary leaning, introduced as a Taylor rule response coefficient on the household debt gap. We find that the costs of leaning in regular times outweigh the benefits of a lower crisis probability. Although the decline in the crisis probability reduces volatility in the economy, this is achieved by lowering the average level of debt, which severely hurts borrowers and leads to a decline in overall welfare

International Spillovers of Large-Scale Asset Purchases

This paper evaluates the international spillover effects of large-scale asset purchases (LSAPs) using a two-country dynamic stochastic general-equilibrium model with nominal and real rigidities, and portfolio balance effects. Portfolio balance effects arise from imperfect substitution between short- and long-term bond portfolios in each country, as well as between domestic and foreign bonds within these portfolios. We show that LSAPs lower both domestic and foreign long-term yields, and stimulate economic activity in both countries. International spillover effects become larger as the steady-state share of long-term U.S. bond holdings increases in the rest-of-the-world portfolio, as the elasticity of substitution between short- and long-term bonds decreases, or as the elasticity of substitution between domestic and foreign bonds increases. We also find that U.S. asset purchases that generate the same output effect as U.S. conventional monetary policy have larger international spillover effects. This is because portfolio balance effects appear to be stronger under unconventional policy, and foreigners' U.S. bond holdings are heavily weighted toward long-term bonds

Housing and tax policy

In this paper, we investigate the effects of housing-related tax policy measures on macroeconomic aggregates using a dynamic general-equilibrium model. The model features borrowing and lending across heterogeneous households, financial frictions in the form of collateral constraints tied to house prices, and a rental housing market alongside owner-occupied housing. Using our model, we analyze the effects of changes in housing-related tax policy measures on the level of output, tax revenue and household debt, along with other macroeconomic aggregates. The tax policies we consider are (i) increasing property tax rates, (ii) eliminating the mortgage interest deduction, (iii) eliminating the depreciation allowance for rental income, (iv) instituting taxation of imputed rental income from owner-occupied housing and (v) eliminating the property tax deduction. We find that among these fiscal tools, eliminating the mortgage interest deduction would be the most effective in raising tax revenue, and in reducing household debt, per unit of output lost. On the other hand, eliminating the depreciation allowance for rental income would be the least effective. Our experiments also highlight the differential welfare impact of each tax policy on savers, borrowers and renters
