Production Stages and the Transmission of Technological Progress

We develop and estimate a DSGE model which realistically assumes that many goods in the economy are produced through more than one stage of production. Firms produce differentiated goods at an intermediate stage and a final stage, post different prices at both stages, and face stage-specific technological change. Wage-setting households are imperfectly competitive with respect to labor skills. Intermediate-stage technology shocks explain most of short-run output fluctuations, whereas final-stage technology shocks only have a small impact. Despite the dominance of technology shocks, the model predicts a near-zero correlation between hours worked and the return to work and mildly procyclical real wages. The factors mainly responsible for these findings are an input-output linkage between firms operating at the different stages and movements in the relative price of goods. We show that, depending the source, a technology improvement may either have a contractionary or expansionary impact on employment.Business Cycles, Production Stages, Technological Change, Nominal Rigidities

The Welfare Implications of Fiscal Dominance

This paper studies the interdependence between fiscal and monetary policy in a DSGE model with sticky prices and non-zero trend inflation. We characterize the fiscal and monetary policies by a rule whereby a given fraction k of the government debt must be backed by the discounted value of current and future primary surpluses. The remaining fraction of debt is backed by seigniorage revenues. When k = 1, there is no fiscal dominance, since the fiscal authority backs all debt and accommodates (independent) monetary policy, by adjusting current or future primary surpluses to satisfy the government’s intertemporal budget constraint. If k = 0, all debt is backed by the monetary authority and there is complete fiscal dominance. A continuum of possibilities lies between these two polar cases. We numerically show that: 1) the degree of fiscal dominance, as measured by (1 - k), is positively related to trend inflation, and 2) when prices are sticky, k has significant effects on the business cycle dynamics. The model is estimated using Bayesian techniques. Estimates of k imply a high degree of fiscal dominance in both Mexico and South Korea, but almost no fiscal dominance in Canada and the U.S. The country-specific estimates of the structural parameters are used in a second-order approximation of the equilibrium around the deterministic steady-state to evaluate the welfare costs of fiscal dominance. Results suggest significant welfare losses for countries with high degrees of fiscal dominance.Economic models; Fiscal policy; Inflation: costs and benefits; Monetary policy framework

The Welfare Implications of Inflation versus Price-Level Targeting in a Two-Sector, Small Open Economy

The authors analyze the welfare implications of simple monetary policy rules in the context of an estimated model of a small open economy for Canada with traded and non-traded goods, and with sticky prices and wages. They find statistically significant heterogeneity in the degree of price rigidity across sectors. They also find welfare gains in targeting only the non-traded-goods inflation, since prices are found to be more sticky in this production sector, but those gains come at the cost of substantially increased aggregate volatility. The authors look for the welfare-maximizing specification of an interest rate reaction function that allows for a specific price-level target. They find, however, that, overall, the higher welfare is achieved, given the estimated model for the Canadian economy, with a strict inflation-targeting rule where the central bank reacts to the next period's expected deviation from the inflation target and does not target the output gap.Economic models; Exchange rates; Inflation targets

Has Exchange Rate Pass-Through Really Declined in Canada?

Several empirical studies suggest that exchange rate pass-through has declined in recent years in industrialized countries. Results for Canada also indicate that, in the 1990s, import and consumer prices became less responsive to exchange rate movements. These findings are based on reducedform regressions that are typically motivated by partial-equilibrium models of pricing. Bouakez and Rebei instead use a structural, general-equilibrium approach to test the premise that exchange rate pass-through has decreased in Canada. Their approach consists in estimating a dynamic stochastic general-equilibrium model for Canada over two subsamples, which cover the periods before and after the Bank's adoption of inflation targeting. The authors then use impulse-response analysis to assess the stability of exchange rate pass-through across the two subsamples. Their results indicate that pass-through to Canadian import prices has been rather stable, while passthrough to Canadian consumer prices has declined in recent years. Counterfactual experiments reveal that the change in monetary policy regime is largely responsible for this decline.Business fluctuations and cycles; Economic models; Exchange rates; Inflation and prices; International topics
