Given the increasing number of regional trade agreements, economists have been estimating their effects on a wide range of outcomes. This column looks at stock market reactions to the implementation of the Canada-US free trade agreement to evaluate its effects on firms’ profits. Firm profits seem to be hurt by lower tariffs, but increase with cheaper access to intermediates and – for large firms – better access to the US market. The author estimates that CUSFTA increased the yearly profits of Canadian manufacturing by 1.2%.

Economists continue to debate whether stock markets influence the real economy. This column takes a look at initial public offerings (IPOs) and finds that firms can increase the precision of the signals they get from the stock market by imitating each other. This effect has important implications for the structure of industries, innovation strategies, the diversity of product offerings for consumers, and the scope for diversification for investors.

In 2013, policymakers began discussing when and how to ‘taper’ the Federal Reserve’s quantitative easing policy. This column presents evidence on the effect of Fed officials’ public statements on emerging-market financial conditions. Statements by Chairman Bernanke had a large effect on asset prices, whereas the market largely ignored statements by Fed Presidents. Emerging markets with stronger fundamentals experienced larger stock-market declines, larger increases in credit default swap spreads, and larger currency depreciations than countries with weaker fundamentals.

Stress in the interbank market has increased dramatically since July 2011, and bank stock market valuations have fallen by 22% on average for 60 of the most important banks subject to stress tests. This column argues that bank stock valuation has been affected by the banks’ exposure to Greek debt and that Greek banks were particularly affected. Holdings of debt of the other four periphery countries does not, however, appear to be a strong determinant of stock price movements.

How the costs and benefits of regional trade agreements are distributed is a controversial question among economists. CEPR DP8566 analyses the stock market response to a country's signing of an RTA. The authors find that the biggest 'bounce' occurs in a country's stock market when it signs an RTA with an already-strong trading partner, or when the country is poor.

This column examines the impact of stock market valuation changes on consumption and investment in emerging markets. Though the effects are smaller than those in advanced economies, emerging market policymakers ought to pay attention to how equity price swings will transmit business cycles and impact aggregate demand.

Past performance is no guarantee, but history tells us that the equity risk premium has been persistent. This column shows that British investors enjoyed relatively high returns in the nineteenth century, though today’s UK market differs greatly from its formative ancestor.
