The eurozone has a single short-term nominal interest rate, but monetary policy conditions measured by real short-term interest rates varied substantially across countries in the period 2003–2010. We use this cross-country variation in the (local) tightness of monetary policy to examine its influence on equity and money market flows. In line with a powerful risk-shifting channel, we find that fund investors in countries with decreased real interest rates shift their portfolio investment out of the money market and into the riskier equity market, causing significant equity price inflation in countries where investment home bias is the strongest.

This paper provides evidence for a causal effect of equity prices on corporate investment and employment. We use fire sales by distressed equity funds during the 2007–2009 financial crisis to identify substantial exogenous underpricing. Firms whose stocks are most underpriced have considerably lower investment and employment than industry peers not subject to any fire sale discount. The causal effect of underpricing on investment is found to be largely concentrated on the most financially constrained firms.

We develop an equilibrium model in which exchange rates, stock prices and capital flows are jointly determined under incomplete forex risk trading. Incomplete hedging of forex risk, documented for U.S. global mutual funds, has three important implications: 1) exchange rates are almost as volatile as equity prices when the forex liquidity supply is not infinitely price elastic; 2) higher returns in the home equity market relative to the foreign equity market are associated with a home currency depreciation; 3) net equity flows into the foreign market are positively correlated with a foreign currency appreciation. The model predictions are strongly supported at daily, monthly and quarterly frequencies for 17 OECD countries visà-vis the U.S. Moreover, correlations are strongest after 1990 and for countries with higher market capitalization relative to GDP, suggesting that the observed exchange rate dynamics is indeed related to equity market development.

This paper presents new stylized facts on the distribution of the home bias at the fund level. We find (i) a large heterogeneity in the degree of home bias across mutual funds; (ii) a positive correlation between the size of funds and home bias; and (iii) a positive correlation between the size of funds, the number of foreign countries and the number of sectors in which they invest. These facts constitute a challenge for existing theories.

Can Portfolio Rebalancing Explain the Dynamics of Equity Returns, Equity Flows, and Exchange Rates? by Harald Hau and Hélène Rey. Published in volume 94, issue 2, pages 126-133 of American Economic Review, May 2004

The large regional variation in minimum wage levels during the period 2002–8 in China implies that Chinese manufacturing firms experienced competitive shocks as a function of firm location and their low-wage employment share. We find that minimum wage hikes accelerate the input substitution from labour to capital, reduce employment growth and accelerate total factor productivity growth—particularly among the less productive firms under private Chinese or foreign ownership, but not among state-owned enterprises. The heterogeneous firm response to labour cost shocks can be explained by differences in management practices and suggests that management quality and competitive pressure are complementary.

This article evaluates the impact of the Chinese minimum-wage policy on consumption of low-wage households for the period 2002–2009. Using a representative panel of urban households, we find that the consumption response to minimum-wage income hikes increases in the share of minimum-wage income in total household income. In particular, poorer households fully consume their additional income, while meaningful negative employment effects are absent. The large marginal propensity to consume is driven by households with at least one child, while poor, childless households save two-thirds of a minimum-wage hike. The expenditure increase is concentrated in health care and education with potentially long-lasting benefits to household welfare.

We examine international equity allocations at the fund level and show how excess foreign returns influence portfolio rebalancing, capital flows, and currencies. Our equilibrium model of incomplete foreign exchange (FX) risk trading where exchange rate risk partially segments international equity markets is consistent with the observed dynamics of equity returns, exchange rates, and fund-level capital flows. We document that rebalancing is more intense under higher FX volatility and find heterogeneous rebalancing behavior across different fund characteristics. A granular instrumental variable approach identifies a positive currency supply elasticity.

Traditional portfolio balance theory derives a downward sloping currency demand function from limited international asset substitutability. Historically, this theory enjoyed little empirical support. We provide direct evidence by examining the exchange rate effect of a major redefinition of the MSCI Global Equity Index in 2001 and 2002. The index redefinition implied large changes in the representation of different countries in the MSCI Global Equity Index and therefore produced strong exogenous equity flows by index funds. Our event study reveals that countries with a relatively increasing equity representation experienced a relative currency appreciation upon announcement of the index change. Moreover, stock markets that are upweighted (downweighted) feature a higher (lower) permanent comovement of their currency with the basket of other MSCI currencies.

The large increase in common institutional ownership has raised legitimate antitrust concerns. While the exact channel by which common institutional shareholders might influence firm policy remains unclear, a prominent potential mechanism is corporate board representation. Using hand-collected data on shareholders' board representation, we show that instances of institutional investors simultaneously holding board positions in rival companies are exceedingly rare and do not account for the positive correlation between common institutional ownership and firm-pair profitability. Our findings suggest that board representation by institutional investors is unlikely to represent an empirically potent channel of influence on corporate policy.
