International comovements, business cycle and inflation: A historical perspective
No full textUsing a dynamic factor model, we uncover four main empirical regularities on international comovements in a long-run panel of real and nominal variables. First, the contribution of world comovements to domestic output growth has decreased over the post-WWII period. The contribution of regional comovements, however, has increased significantly. Second, the share of inflation variation due to a global factor has become larger since 1985. Third, over most of the post-WWII period, international comovements within regions have accounted for the bulk of fluctuations in business cycle and inflation. Fourth, prices have become significantly less countercyclical during the post-1984 sample, with the largest contribution due to external developments
Understanding International Price Differences Using Barcode Data
Get PDFThe empirical literature in international finance has produced three key results about international price deviations: borders give rise to flagrant violations of the law of one price, distance matters enormously for understanding these deviations, and most papers find that convergence rates back to purchasing power parity are inconsistent with the evidence of micro studies on nominal price stickiness. The data underlying these results are mostly comprised of price indexes and price surveys of goods that may not be identical internationally. In this paper, we revisit these three stylized facts using massive amounts of US and Canadian data that share a common barcode classification. We find that none of these three main stylized facts survive. We use our barcode level data to replicate prior work and explain what assumptions caused researchers to find different results from those we find in this paper. Overall, our work is supportive of simple pricing models where the degree of market segmentation across the border is similar to that within borders.
Macroeconomic information, structural change, and the prediction of fiscal aggregates
Get PDFAbstractPrevious research on the prediction of fiscal aggregates has shown evidence that simple autoregressive models often provide better forecasts of fiscal variables than multivariate specifications. We argue that the multivariate models considered by previous studies are small-scale, probably burdened by overparameterization, and not robust to structural changes. Bayesian Vector Autoregressions (BVARs), on the other hand, allow the information contained in a large data set to be summarized efficiently, and can also allow for time variation in both the coefficients and the volatilities. In this paper we explore the performance of BVARs with constant and drifting coefficients for forecasting key fiscal variables such as government revenues, expenditures, and interest payments on the outstanding debt. We focus on both point and density forecasting, as assessments of a country’s fiscal stability and overall credit risk should typically be based on the specification of a whole probability distribution for the future state of the economy. Using data from the US and the largest European countries, we show that both the adoption of a large system and the introduction of time variation help in forecasting, with the former playing a relatively more important role in point forecasting, and the latter being more important for density forecasting

The Impact of Uncertainty Shocks under Measurement Error: A Proxy SVAR Approach
Get PDFA growing literature considers the impact of uncertainty using SVAR models that include proxies for uncertainty shocks as endogenous variables. In this paper we consider the impact of measurement error in these proxies on the estimated impulse responses. We show via a Monte-Carlo experiment that measurement error can result in attenuation bias in impulse responses. In contrast, the proxy SVAR that uses the
uncertainty shock proxy as an instrument does not su¤er from this bias. Applying this latter method to the Bloom (2009) data-set results in impulse responses to uncertainty shocks that are larger in magnitude and more persistent than those obtained from a
recursive SVAR
One TV, One Price?
Get PDFWe use a unique dataset on television prices across European countries and regions to investigate the sources of differences in price levels. Our findings are as follows: (i) Quality is a crucial determinant of price differences. Even in an integrated economic zone as Europe, rich economies tend to consume higher quality goods. This effect accounts for the lion’s share of international price dispersion. (ii) Sizable international price differentials subsist even for the same television sets. The average bilateral price difference is as high as 80 euros, or 8% of the average TV price in our sample. (iii) EMU countries display lower price dispersion than non-EMU countries. (iv) absolute price differentials and relative price volatility are positively correlated with exchange rate volatility, but not with conventional measures of transport costs. (v) Importantly we show brand premia are sizable. They differ markedly across borders, in a way that does not correlate with transport costs, nor exchange rate movements. Taken together, the evidence is consistent firms exploiting market power through brand values to price discriminate across borders.
Random walks and half-lives in Chilean and Mexican peso real exchange rates: 1980-2003
Get PDFSeveral papers have shown that high-inflation contributes to mean reversion in real exchange rates. This paper studies the Chilean peso (CLP) and Mexican peso (MXN) real exchange rates over 1980-2003. Three datasets are used: two with quarterly and monthly bilateral data (against the U.S. dollar) with consumer and producer price indices and another with monthly real effective rate exchange rates (REER). Unit root tests do not reject the root in levels for both currencies. Half-lives, however, contrast markedly: at 5 years or infinity for the Chilean peso and between 1 and 3 years for the Mexican peso. These findings suggest that the sharp depreciations in MXN and Mexico’s relatively higher inflation record may have amplified monetary forces in the dynamics of the real exchange rates.ARMA models, half-lives, random walks, real exchange rates, unit roots
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
