We use controlled laboratory experiments to test the causal effects of central bank communication on economic expectations and to distinguish the underlying mechanisms of those effects. In an experiment where subjects learn to forecast economic variables, we find that central bank communication has a stabilizing effect on individual and aggregate outcomes and that the size of the effect varies with the type of communication.

We develop high-frequency, news-based indicators using natural language processing methods to analyze news media texts. Our indicators track both supply (raw, intermediate and final goods) and labour shortages over time. They also provide weekly time-varying topic narratives about various types of shortages.

This issue features a summary of the Bank’s annual conference, which took place in November 2011 and dealt with payments systems, and two articles that present research by Bank staff on global current account imbalances and macrofinancial risk assessment. The fourth article in this issue reviews the recent experience with inflation targeting.

This article by the Bank's Web master details the development of the Bank's Web site and highlights some of its special features. It includes a description of dataBANK, a custom-built interface to the Bank's economic databases that gives visitors access to 220 data series. It also provides a mini tour of monetary policy material "on site," as well as a taste of things to come. Above all, this article invites you to come and visit our site.

I chose to speak about globalization at the outset of my tenure because it will continue to be one of the forces shaping our economy and economic policy for years to come. Steady advances in transportation, communication, and information technologies, underpinned by the more widespread adoption of free-market economic policies, are shrinking the globe and expanding the global economy.

The financial crisis of 2007-09 and the subsequent extended period of historically low real interest rates have revived the question of whether economic agents are willing to take on more risk when interest rates remain low for a prolonged time period. This increased appetite for risk, which causes economic agents to search for investment assets and strategies that generate higher investment returns, has been called the risk-taking channel of monetary policy. Recent academic research on banks suggests that lending policies in times of low interest rates can be consistent with the existence of a risk-taking channel of monetary policy in Europe, South America, the United States and Canada. Specifically, studies find that the terms of loans to risky borrowers become less stringent in periods of low interest rates. This risk-taking channel may amplify the effects of traditional transmission mechanisms, resulting in the creation of excessive credit.

We review the nascent but fast-growing literature on central bank digital currencies (CBDCs), focusing on their potential impacts on private banks. We evaluate these impacts in three areas of traditional banking: payments, lending and liquidity and maturity transformation. We also take a broader look at CBDCs and highlight two promising directions for future research.

Can Bitcoin survive? Some say it will become vulnerable to attacks as the rewards for processing Bitcoin transactions continue to decline. The economics of fixed costs suggest the specialized hardware used to mine Bitcoin may be key to its survival.

We analyze the evolution of macroeconomic uncertainty in the United States, based on the forecast errors of consensus survey forecasts of different economic indicators. Comprehensive information contained in the survey forecasts enables us to capture a real-time subjective measure of uncertainty in a simple framework.

This paper outlines and assesses the various channels through which digitalization can affect prices of goods and services.
