Adoption of inflation targeting and tax revenue performance in emerging market economies: An empirical investigation

This paper investigates whether the adoption of inflation targeting (IT), by strengthening central bank independence and maintaining inflation at low levels, has encouraged the governments of emerging economies to improve the collection of domestic tax revenue in order to recoup the loss of seigniorage revenue. Using the propensity score matching methodology, a micro-econometric methodology recently used in macroeconomics, we evaluate the ‘treatment effect’ of IT on fiscal mobilization in emerging countries that have adopted this monetary policy framework. Our empirical analysis, conducted on a sample of 59 countries (19 IT and 40 non-IT countries) for the period from 1980 to 2009, shows that on average IT adoption has had a large and significant positive effect on public revenue collection. Our results are confirmed by extensive robustness tests.     

Exchange rate pass-through, menu costs and threshold cointegration

This paper investigates exchange rate pass-through (ERPT) in the presence of menu costs. Assuming exports prices are negotiated in the exporter’s currency, menu costs give rise to two thresholds around (within) which incomplete ERPT is (not) observed. An error correcting process is triggered from a deviation in the ERPT cointegrating relation only when the deviation is large enough in absolute value to fall outside of a band defined by symmetric thresholds. Threshold autoregressive (TAR) cointegration techniques are used to investigate Quebec and Ontario pork meat export prices in the US and Japanese markets. Through Monte Carlo simulations, we find that our Equilibrium-TAR tests have greater power than a standard unit root test. Our empirical application suggests that Canadian pork exporters exercise market power in the US market. The evidence of incomplete ERPT in the Japanese market is weaker and differs across provinces. Evidence of thresholds is reported for both destinations, thus indicating the existence of significant menu costs for Canadian pork exporters in these markets.     

Is there still a productivity paradox? two methods for a transatlantic comparison

Economic activity accelerated in the United States, in the second part of the cycle, after 1995, within an environment of decreasing inflation. France has followed a qualitatively similar path since 1997, also clearly suggesting the effects of a positive supply shock. The spread of new information and communication technologies (NICT) partly explains these singular events. On one hand, a calculation of contributions to output growth suggests that they would explain about half of the increase in activity in the United States and one-fifth in France. On the other hand, a trend/cycle decomposition reveals that the structural acceleration in output and productivity gains in the United States are very much restricted to industries producing NICT and there is a rather small break in productivity gains. In France, where differences between sectors are not so clear-cut, the diffusion of NICT has been accompanied by a slowdown in trends in productivity gains. In both cases, there is little room left for the effects of the diffusion of technical progress associated with NICT.     

Options introduction and volatility in the EU ETS

To improve risk management in the European Union Emissions Trading Scheme (EU ETS), the European Climate Exchange (ECX) has introduced option instruments in October 2006. The central question we address is: can we identify a potential destabilizing effect of the introduction of options on the underlying market (EUA futures)? Indeed, the literature on commodities futures suggest that the introduction of derivatives may either decrease (due to more market depth) or increase (due to more speculation) volatility. As the identification of these effects ultimately remains an empirical question, we use daily data from April 2005 to April 2008 to document volatility behavior in the EU ETS. By instrumenting various GARCH models, endogenous break tests, and rolling window estimations, our results overall suggest that the introduction of the option market had the effect of decreasing the level of volatility in the EU ETS while impacting its dynamics. These findings are fairly robust to other likely influences linked to energy and commodity markets.     

Central bank credibility and the expectations channel: evidence based on a new credibility index

This article investigates the relationship between central bank credibility and the volatility of the key monetary policy instrument. First, we propose a time-varying measure of central bank credibility based on the gap between inflation expectations and the official inflation target. While this new index addresses the main limitations of the existing indicators, it also appears particularly suited to assess the monetary experiences of a large sample of inflation-targeting emerging countries. Second, by means of EGARCH estimations, we formally prove the existence of a negative effect of credibility on the volatility of the short-term interest rate. In line with the expectations channel of monetary policy, the higher the credibility of the central bank, the lower the need to move its instruments to effectively fulfill its objective.     

The Effectiveness of Social Media Storytelling in Strategic Innovation Communication: Narrative Form Matters

Storytelling is widely believed to be an effective strategy in innovation communication. The use of high-quality narratives in particular is recommended to facilitate the understanding of an innovation, facilitate trust in it, and promote the perception of innovative strength as well as the development of positive attitudes. However, to date virtually no empirical evidence has been presented to support these assumptions. Therefore, we conducted an experiment in which participants were exposed to messages about an innovation that varied in narrative quality (low vs. medium vs. high), and the messages were told in different forms that are typical of social media (nonserial vs. serial) to take account of the ever-increasing importance of these channels in innovation communication. The results show that the understanding of an innovation increases linearly with a message’s narrative quality, serial storytelling impedes understanding, and narrative quality is conducive to the attitude towards the innovator when the story is told in nonserial form and has a detrimental effect when told in serial form. Thus, the results show that the current view on storytelling’s potential is overly optimistic and that using high-quality narratives can, under certain conditions, also have adverse effects. The practical implications of these findings are discussed.     

A pair-wise approach to output convergence between European regions

We apply the Pesaran (2007) pair-wise approach of convergence to the per capita outputs of 195 European regions for the period 1980-2006. Pesaran's approach is based on the computation of the percentage ratio of output gaps which fulfil a given convergence criterion. A high ratio will be interpreted in favour of convergence. In a first step, we define stochastic convergence between two regions as level stationarity of their output gap. Deviations from its equilibrium value will only have a temporary effect. Results from several usual unit root or stationarity tests show us that the percentage ratio of level stationary output gaps is low, which stands against this definition of convergence. However, this convergence criterion excludes the possibility of changes in output gap equilibrium value or catching up between regions. To fit these cases, we combine the pair-wise approach with unit root or stationarity tests with structural breaks. Structural breaks are modelled by dummies (Zivot and Andrews, 1992; Kurozumi,2002) or as smooth structural breaks (Christopoulos and León-Ledesma, 2009). Overall results are not changed as convergence is not accepted more often. Finally, we consider the autocorrelation function approach of Caggiano and Leonida (2009). Autocorrelations and their confidence intervals are estimated for each output gap. Convergence between two regions is accepted if their per capita output gap autocorrelations become nonsignificantly different from zero after some lag. Results show that a high percentage of regions satisfy this convergence criterion. Contrary to the conclusions which could be made from previous results, shocks to output gaps seem to disappear as time passes.
