This paper examines the evidence on asymmetries in the effects of activity on inflation. Data for the G-7 countries are found to strongly support the view that the inflation-activity relationship is nonlinear, with high levels of activity raising inflation by more than low levels decrease it. In the face of such asymmetries, the average level of output in an economy subject to demand shocks will be below the level of output at which there is no tendency for inflation to rise or fall, contrary to the implications of linear models. One implication of these results is that policymakers can raise the average level of output over time by responding promptly to demand shocks, thus reducing the variance of output around trend.

A crucial challenge for economists is figuring out how people interpret the world and form expectations that will likely influence their economic activity. Inflation, asset prices, exchange rates, investment, and consumption are just some of the economic variables that are largely explained by expectations. Here George Evans and Seppo Honkapohja bring new explanatory power to a variety of expectation formation models by focusing on the learning factor. Whereas the rational expectations paradigm offers the prevailing method to determining expectations, it assumes very theoretical knowledge on the part of economic actors. Evans and Honkapohja contribute to a growing body of research positing that households and firms learn by making forecasts using observed data, updating their forecast rules over time in response to errors. This book is the first systematic development of the new statistical learning approach. Depending on the particular economic structure, the economy may converge to a standard rational-expectations or a "rational bubble" solution, or exhibit persistent learning dynamics. The learning approach also provides tools to assess the importance of new models with expectational indeterminacy, in which expectations are an independent cause of macroeconomic fluctuations. Moreover, learning dynamics provide a theory for the evolution of expectations and selection between alternative equilibria, with implications for business cycles, asset price volatility, and policy. This book provides an authoritative treatment of this emerging field, developing the analytical techniques in detail and using them to synthesize and extend existing research.

This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest income quintiles with the view to assess the distributional impact of the pass-through. To undertake this analysis, the paper provides an update to the Global Monthly Retail Fuel Price Database, expanding the product coverage to premium and regular fuels, the time dimension to December 2020, and the sample to 190 countries. Three key findings stand out. First, the response of inflation to gasoline price shocks is smaller, but more persistent and broad-based in developing economies than in advanced economies. Second, we show that past studies using crude oil prices instead of retail fuel prices to estimate the pass-through to inflation significantly underestimate it. Third, while the purchasing power of all households declines as fuel prices increase, the distributional impact is progressive. But the progressivity phases out within 6 months after the shock in advanced economies, whereas it persists beyond a year in developing countries.

Why do consumer prices and wages adjust so slowly to changes in market conditions? The rigidity or stickiness of price setting in business is central to Keynesian economic theory and a key to understanding how monetary policy works, yet economists have made little headway in determining why it occurs. Asking About Prices offers a groundbreaking empirical approach to a puzzle for which theories abound but facts are scarce. Leading economist Alan Blinder, along with co-authors Elie Canetti, David Lebow, and Jeremy B. Rudd, interviewed a national, multi-industry sample of 200 CEOs, company heads, and other corporate price setters to test the validity of twelve prominent theories of price stickiness. Using everyday language and pertinent scenarios, the carefully designed survey asked decisionmakers how prominently these theoretical concerns entered into their own attitudes and thought processes. Do businesses tend to view the costs of changing prices as prohibitive? Do they worry that lower prices will be equated with poorer quality goods? Are firms more likely to try alternate strategies to changing prices, such as warehousing excess inventory or improving their quality of service? To what extent are prices held in place by contractual agreements, or by invisible handshakes? Asking About Prices offers a gold mine of previously unavailable information. It affirms the widespread presence of price stickiness in American industry, and offers the only available guide to such business details as what fraction of goods are sold by fixed price contract, how often transactions involve repeat customers, and how and when firms review their prices. Some results are surprising: contrary to popular wisdom, prices do not increase more easily than they decrease, and firms do not appear to practice anticipatory pricing, even when they can foresee cost increases. Asking About Prices also offers a chapter-by-chapter review of the survey findings for each of the twelve theories of price stickiness. The authors determine which theories are most popular with actual price setters, how practices vary within different business sectors, across firms of different sizes, and so on. They also direct economists' attention toward a rationale for price stickiness that does not stem from conventional theory, namely a strong reluctance by firms to antagonize or inconvenience their customers. By illuminating how company executives actually think about price setting, Asking About Prices provides an elegant model of a valuable new approach to conducting economic research.

First published in 1998, this wide-ranging and in-depth volume from specialists in economics and statistics examines leading indicators, the timing of cyclical turning points, firm behaviour, financial indicators, economic policy recommendations, transition economies and the service sector in relation to Finland’s bid for European Monetary Union membership.

This paper focuses on identifying potential asymmetric responses of non-commodity output growth in times of positive and negative commodity terms-of-trade shocks. Using a sample of 27 oil-exporting countries and a panel VAR method, the study finds: 1) the short-and medium-run response of real non-commodity GDP growth is larger for negative shocks than positive shocks; 2) this asymmetry is more pronounced in countries with weak pre-existing fundamentals–high levels of public debt and low levels of international reserves–which also serve to amplify the volatility of the response; 3) the output response to positive shocks is stronger following a sustained period of CTOT increases, while the impact of negative shocks on output are more damaging when they occur after a period of CTOT decline.
