The effects of monetary policy in the Czech Republic: an empirical study

In this paper, we examine the effects of Czech monetary policy on the economy within the vector auto regression (VAR), structural VAR, Bayesian VAR with sign restrictions, and factor-augmented VAR, frameworks. We document a well-functioning transmission mechanism similar to the euro area countries, especially in terms of persistence of monetary policy shocks. Subject to various sensitivity tests, we find that a contractionary monetary policy shock has a negative effect on the degree of economic activity and the price level, both with a peak response after one year or so. Regarding prices at the sectoral level, tradables adjust faster than non-tradables, which is in line with microeconomic evidence on price stickiness. There is no price puzzle, as our data come from a single monetary policy regime. There is a rationale in using the real-time output gap instead of current GDP growth, as using the former results in much more precise estimates. The results indicate a rather persistent appreciation of the domestic currency after a monetary tightening, with a gradual depreciation afterwards.     

Measuring the effects of monetary policy in Pakistan: a factor-augmented vector autoregressive approach

This paper examines the effects of monetary policy on macroeconomic variables in Pakistan’s economy using a data-rich environment. We used the factor-augmented vector autoregressive (FAVAR) methodology, which contains 115 monthly variables for the period 1992:01 to 2010:12. We compared the results of VAR and FAVAR model and the results showed that FAVAR model explains the effects of monetary policy which are consistent with the theory and better than the VAR model. VAR model shows the existence of price puzzle and liquidity puzzle in Pakistan while FAVAR model did not provide any evidence of puzzles. Interest rate negatively influences prices, hence interest rate is a good instrument for controlling inflation in Pakistan but it takes a lag of 5 months. The transmission of monetary policy shock is faster in case of prices as compared to output in Pakistan. FAVAR model supports the effectiveness of interest rate channel in Pakistan.

Does tax policy affect credit spreads? Evidence from the US and UK

This paper studies how exogenous tax changes affect credit market conditions in the US and UK. Using both structural VAR and structural factor-augmented VAR (FAVAR) model, we find that tax-policy shocks have significant effects on the credit spread. Specifically, the credit spread responds first positively and then negatively to an exogenous tax increase in the two countries. Moreover, the impulse responses of the credit spread to tax-policy shocks do not always accord well with the impulse responses of the output. This indicates that there are channels of tax policy transmission to the credit spread other than through its impact on the business cycle.     

Real Effects of Monetary Policy in New Zealand

This article analyses the dynamic effects of unexpected domestic and foreign monetary policy shocks on industrial output in New Zealand based on a new open economy macroeconomic model. Empirical analyses are performed using unrestricted recursive open economy vector autoregressive models involving policy and non‐policy variables for New Zealand and four of its most important trading partners (that is, Australia, Japan, the United Kingdom and the United States). The empirical findings are in accord with the qualitative predictions of the conventional monetary transmission mechanism applicable to a small open economy. Consequently, no empirical anomalies are observed in the dynamic behaviour of New Zealand industrial output in response to restrictive monetary innovations of domestic and foreign origin.

Employment responses to aggregate and sectoral technology shocks

This paper investigates the responses of sectoral employment in US manufacturing to a technology shock by its type: aggregate or sectoral. In order to distinguish between aggregate and sectoral shocks, we construct independent VAR models for identifying each shock separately: a factor-augmented vector autoregression (FAVAR) for aggregate shocks and a sectoral SVAR for sectoral shocks. Our aggregate model in particular extends the conventional small-scale VAR to the FAVAR framework of Bernanke et al. (2005) so that it can address the potential bias from omitted variables. The main findings are as follows: most industries exhibit negative employment responses to an aggregate technology shock while exhibiting positive responses to a sectoral technology shock. By comparing our FAVAR framework with Chang and Hong’s (2006) small-scale VAR, we show that applying the FAVAR results in significant differences in the estimated responses to an aggregate technology shock. Real rigidities (such as slow diffusion of new technology or frictional labor reallocation), rather than nominal rigidities (such as sticky prices), are crucial in accounting for the cross-industry difference in employment responses. In particular, the slow diffusion of new technology is closely related to the sluggish response of sectoral employment.     

Long- and short-run determinants of capital flows to Latin America: a long-run structural GVAR model

This article documents the determinants of capital flows to Argentina, Brazil and Mexico, assessing the relative importance of domestic and international factors through the estimation of a long-run structural Global VAR model of the world economy. The results show that in the long-run international factors prevail on domestic factors as determinants of the equilibrium behaviour of Net Foreign Assets (NFA) and also provide overwhelming evidence that domestic shocks are predominantly responsible for their short-run dynamics. Although all previous studies focus on the US economic influence, one striking result of this article is that the US variables are by no means the main external factors affecting Latin American NFA.     

Idiosyncratic and international transmission of shocks in the G7: Does EMU matter?

This paper analyzes the transmission of shocks across the Group of Seven industrialized countries (G7) before and after the introduction of the euro. We estimate global vector autoregressive (VAR) models for different periods to investigate changes in the domestic and international adjustment of macroeconomic variables following supply, demand, and nominal shocks. The shocks are identified with robust sign restrictions, which we derive from a small open economy dynamic stochastic general equilibrium (DSGE) model. Specifically, we analyze the adjustment of output, inflation, and the real effective exchange rate following those shocks. Our results indicate that changes in the adjustment are due to global convergence rather than to regional‐specific convergence.     

Can trade openness affect the monetary transmission mechanism?

This paper explores how trade openness influences the monetary transmission mechanism. The theoretical analysis develops an open economy New Keynesian model that features one‐way offshoring from an advanced economy to a less developed one. The model suggests that greater openness to regular trade or to offshoring reduces the effect of monetary policy on domestic economies, although these two influences affect the monetary transmission mechanism via different channels. The empirical section estimates an interacted‐panel VAR model with U.S. industry data and confirms that greater exposure to regular trade or to offshoring significantly reduces the effect of monetary policy.     

Asymmetric and Time‐Varying Causality between Inflation and Inflation Uncertainty in G‐7 Countries

We use Granger causality tests within a conditional Gaussian Markov switching vector autoregressive (MS‐VAR) model using monthly data for G‐7 countries covering the period 1959:12–2008:10 to examine the relationship between inflation and inflation‐uncertainty. The MS‐VAR model allows us to model parameter time‐variation so as to reflect changes in Granger causality, assuming that these changes are stochastic and governed by an unobservable Markov chain. Inflation uncertainty is measured as the conditional variance generated by a Fractionally Integrated Smooth Transition Autoregressive Moving Average‐Asymmetric Power ARCH (FISTARMA‐APARCH) model. The distinguishing feature of our approach from the previous studies is the determination of the sign of the Granger causality relationship between inflation and its uncertainty over time. First, using a rolling VAR model, we show that the relationship between inflation and inflation uncertainty is time varying with frequent breaks. Second, using the MS‐VAR model, we obtain strong evidence in favour of the Holland's ‘stabilizing Fed hypothesis’ for Canada, France, Germany, Japan, United Kingdom, and the United States. We also find evidence in favour of the Friedman hypothesis for Canada and the United States.     

Inventing together: exploring the nature of international knowledge spillovers in Latin America

This paper studies the nature, sources and determinants of international patenting activity in Latin American countries (LACs) and examines the extent to which LACs benefit from R&D that is performed in the G-5 countries (France, Germany, Japan, the United Kingdom, and the United States). By using patents and patent citations from the United States Patent and Trademark Office, we trace sectoral knowledge flows from G-5 countries to LACs. We study the impact of three channels of knowledge flows: foreign R&D, patent citation-related spillovers, and face-to-face contact spillovers. Our results, based on data for Argentina, Brazil, Chile, Colombia and Mexico, suggest that international knowledge spillovers from the G-5 countries were a significant determinant of inventive activity during the period 1988–2003. We find that the stock of ideas produced in the USA has a strong impact on the international patenting activity of these countries. Moreover, controlling for US-driven R&D effects, bilateral patent citations and face-to-face relationships between inventors are both important additional mechanisms of knowledge transmission. Some of our results suggest that the latter mechanism is more important than the former.     

NORTH AMERICAN FREE TRADE AGREEMENT BILATERAL TRADE EFFECTS

This study evaluates the effects of the North American Free Trade Agreement (NAFTA) on bilateral trade between the United States and Canada and between the United States and Mexico. Trade flow estimates are from a vector autoregression (VAR) model. The VAR methodology allows modeling bilateral trade in a flexible manner that incorporates both the interaction between different variables and the dynamics of trade, output, prices, and the exchange rate. After testing the outside sample forecasting ability of the models, the study produces dynamic forecasts of bilateral trade. It then compares forecasts incorporating the effects of the NAFTA with baseline forecasts. The results suggest expanded trade for all three countries and an improvement in the U.S. trade position with both Canada and Mexico.     

What to expect from an international system of tradable permits for carbon emissions

We use an econometrically-estimated multi-region, multi-sector general equilibrium model of the world economy to examine the effects of using a system of internationally-tradable emissions permits to control world carbon dioxide emissions. We focus, in particular, on the effects of the system on flows of trade and international capital. Our results show that international trade and capital flows significantly alter projections of the domestic effects of emissions mitigation policy, compared with analyses that ignore international capital flows, and that under some systems of international permit trading the United States is likely to become a significant permit seller, the opposite of the conventional wisdom.

THE INTERNATIONALIZATION OF AGRICULTURAL TECHNOLOGY: PATENTS, R&D SPILLOVERS, AND THEIR EFFECTS ON PRODUCTIVITY IN THE EUROPEAN UNION AND UNITED STATES

Multilateral indices of total factor productivity (TFP) allow efficiency comparisons between ten European Union countries and the United States from 1973 to 1993. Differences in TFP levels are then explained by land quality differences, public research and development (R&D) expenditures, education levels, private-sector patents, international spillovers of public R&D, and private-sector technology transfer. There is evidence that public R&D results in limited knowledge spillovers between the European countries and the United States. However, the use of international patent data from the Yale Technology Concordance shows not only that patents matter, but also that private sector technology transfer may be the dominant force in explaining TFP trends. The United States and the European Union countries with more advanced research systems (Netherlands, Denmark, France, and Belgium) converge in a high-growth club, while Germany, Luxembourg, Greece, Italy, Ireland, and the United Kingdom form the slow-growth group. Ignoring knowledge spillovers and technology transfer leads to biased estimates of R&D elasticities, which is hardly surprising since the private sector is now spending more than the public in some of these countries. Thus, the estimated rate of return to public agricultural R&D falls from over 60% in the closed economy model to 10% in the model that takes account of international spillovers. (JEL Q16)     

The political economy of conditionality: An empirical analysis of World Bank loan disbursements

Traditional aid conditionality has been attacked as ineffective in part because aid agencies – notably the World Bank – often fail to enforce conditions. This pattern undermines the credibility of conditionality, weakening incentives to implement policy reforms. The standard critique attributes this time inconsistency to bureaucratic factors within the aid agency such as pressure to lend, defensive lending, or short-sighted altruism. Pressure from powerful donors provides another potential explanation for lax enforcement. This paper presents an empirical analysis of the political economy of conditionality in international organizations using the case of the World Bank and the United States. The analysis examines panel data on World Bank disbursements to 97 countries receiving structural adjustment loans between 1984 and 2005. Using UN voting as an indicator of alignment with the U.S., the paper presents evidence that World Bank structural adjustment loan disbursements are less dependent on macroeconomic performance in countries aligned with the United States.     

A structural VAR business cycle model for a volatile small open economy

New Zealand is a small economy exposed to a volatile climate, relatively volatile international trade prices, and its exposure to international financial markets has increased markedly since economic reforms in the 1980s. This paper applies identification techniques suggested by Cushman and Zha [Cushman, D.O. and Zha T.A., 1997. Identifying monetary policy in a small open economy under flexible exchange rates, Journal of Monetary Economics, 39, pp. 433–448.], Zha [Zha, T.A., (1999). Block recursion and structural vector autoregression, Journal of Econometrics, 90, pp. 291–316.] and Dungey and Pagan [Dungey, M. and Pagan, A., 2000. A structural VAR model of the Australian economy, The Economic Record, 76, pp. 321–342.] to develop a large four block structural VAR model of the New Zealand business cycle to capture these features. The model reveals that climate and international trade price shocks have been more important sources of business cycles fluctuations than international or domestic financial shocks. Furthermore, the model does not encounter the price and exchange rate puzzles that have bedevilled attempts to identify monetary policy shocks in small open economy SVAR models.     

Exports and economic growth in industrialized countries

The prima-facie causal relationships between growth, exports and factor inputs (capital and labour) are investigated in five industrialized countries (germany, Itlay, Japan, United Kingdom and United States) over the period 1960–87 by analysing a four-variable vector autoregressive (VAR) model for each country. Our results indicate that Germany and Japan experienced export-led growth. Reverse causality between exports and growth is found in the case of the US and UK, while to causal relationship between exports and output is found for Itlay.
