Firm boundaries matter: Evidence from conglomerates and R&D activity

This paper examines the impact of the conglomerate form on the scale and novelty of corporate Research and Development (R&D) activity. I exploit a quasi-experiment involving failed mergers to generate exogenous variation in acquisition outcomes of target firms. A difference-in-differences estimation reveals that, relative to failed targets, firms acquired in diversifying mergers produce both a smaller number of innovations and also less-novel innovations, where innovations are measured using patent-based metrics. The treatment effect is amplified if the acquiring conglomerate operates a more active internal capital market and is largely driven by inventors becoming less productive after the merger rather than inventor exits. Concurrently, acquirers move R&D activity outside the boundary of the firm via the use of strategic alliances and joint ventures. There is complementary evidence that conglomerates with more novel R&D tend to operate with decentralized R&D budgets. These findings suggest that conglomerate organizational form affects the allocation and productivity of resources.     

Exchange rate undervaluation and R&D activity

We examine how real exchange rate undervaluation policy affects research and development (R&D) activity. Using a panel data set comprising 49 developed and developing countries covering 1996–2011, we show that undervaluing the exchange rate retards technological innovation. Such a negative impact is particularly prominent for developed countries. This paper provides new insights into the real effects of undervaluation policy on the economy. An implication of our work is that countries implementing exchange rate undervaluation policy should be mindful of its potential negative effects on research and development activity.     

CEO risk incentives and firm performance following R&D increases

In this study we analyze how CEO risk incentives affect the efficiency of research and development (R&D) investments. We examine a sample of 843 cases in which firms increase their R&D investments by an economically significant amount over the period of 1995–2006. We find that firms with higher sensitivity of CEO compensation portfolio value to stock volatility (vega) are more likely to have large increases in R&D investments. More importantly, we find that high-vega firms experience lower abnormal stock returns and lower operating performance compared to their low-vega counterparts following the R&D increases. Our main results hold in a variety of robustness tests. The results are consistent with the conjecture that high-vega compensation portfolios may induce managers to overinvest in inefficient R&D projects and therefore hurt firm performance.     

House prices,bank instability,and economic growth: Evidence from the threshold model

This paper examines the effects of house prices on bank instability when gauged at various levels of income growth. Bank stability may respond differently to house price changes or deviations from fundamental values in an economic boom environment than in a bust circumstance. A threshold estimation technique developed by Hansen (1999) is applied to a panel of 286 U.S. Metropolitan Statistical Areas (MSAs) over the period 1990Q1–2010Q4. We consider two house price indicators: the house price changes and the house price deviations from long-run equilibrium. The results suggest the existence of income growth threshold effects in the relationship between house prices and bank instability. Specifically, there are two income growth thresholds when using the house price changes and one income growth threshold when the house price deviations are applied. Robustness results using the non-MSAs sample from 1995Q1 to 2010Q4 provide further evidence of income growth threshold effects.     

Stock returns’ sensitivities to crisis shocks: Evidence from developed and emerging markets

We consider three “crisis shocks” related to key features of the 2007–2008 crisis, for emerging and developed economies: (1) the collapse of global trade, (2) the contraction of credit supply, and (3) selling pressure on firms’ equity. Using an international cross-section of firms, we find that returns’ sensitivities to these shocks imply large and statistically significant influences on residual equity returns during the crisis period (after controlling for normal risk factors that are associated with expected returns). Similar analysis for several placebo periods shows that these effects are generally less severe or absent in non-crisis periods. Relative to developed economies, emerging markets are more responsive to global trade conditions (in crisis and in placebo periods), but less responsive to selling pressures. An analysis of portfolios of firms during various placebo periods indicates that investors are not compensated for the risks associated with the crisis shocks. Finally, a month-by-month analysis of returns during the crisis period shows that the time variation of the importance of each of the sensitivities to shocks tracks related changes in the global economic environment.     

Informed finance and technological change: Evidence from credit relationships

This paper empirically investigates the effect of “informed finance” on technological change. The theoretical literature offers conflicting predictions on whether the information of financiers fosters or inhibits firms’ innovation. Using data from a sample of Italian manufacturing firms, we find that the information of firms’ main banks, proxied by the duration of credit relationships, promotes innovation. This positive effect is economically and statistically more significant for product than for process innovations. Nonetheless, the role of relationship banks in innovation is quite unsophisticated: they do not foster internal research but rather fund the relevant investments that the introduction and acquisition of new technologies entails.     

Capitalisation of R&D and the informativeness of stock prices: Pre- and post-IFRS evidence

We examine whether requiring (IFRS) versus allowing (UK GAAP) conditional capitalisation of development expenditure affects the extent to which capitalisation conveys more information about future earnings, relative to expensing. We show that capitalisation results in current returns incorporating more future earnings information than expensing under UK GAAP but not under IFRS. i.e., the amount of information incorporated into market prices of capitalisers is the same as that from firms expensing R&D under IFRS. This result holds irrespective of a firm’s earnings management incentives or strength of corporate governance for the period under IFRS. We argue that this is because investors experience greater uncertainty regarding the realisation of future economic benefits associated with the development costs capitalised in the post-IFRS period. Consistent with this, we do find a positive association between capitalised R&D and future earnings variability in the post-IFRS period only, as well as short-term positive abnormal returns for capitalisers relative to expensers in the pre-IFRS period only. Overall, these findings suggest that when moving away from a standard that offers an overt option to capitalise or expense, capitalisation comes with greater uncertainty, which is resolved only in the long term.     

The value-relevance of R&D and advertising expenditures: Evidence from Korea

This study examines the value-relevance of R&D and advertising expenditures of Korean firms, using a regression model based on the Ohlson [Contemp. Account. Res. (1995) 661] equity-valuation framework. Results indicate that R&D expenditures are positively associated with stock price, suggesting that capitalizing R&D expenditures is appropriate. The association is stronger for the portion of R&D expenditures that is capitalized, rather than expensed, suggesting that investors agree with management that the capitalized expenditures represent greater future economic benefits. Investors also appear to interpret fully expensed R&D expenditures as positive net present-value investments, however, suggesting that these expenditure should also be capitalized. Additional results indicate that advertising expenditures are negatively associated with stock price, and the magnitude of this negative association is similar to the association between other expenses and stock price. These findings suggest that investors believe the economic benefits of advertising expenditures expire in the current period, similar to other expenses.     

Multinational banking and the international transmission of financial shocks: Evidence from foreign bank subsidiaries

Using bank-level data on 368 foreign subsidiaries of 68 multinational banks in 47 emerging economies during 1994–2008, we present consistent evidence that internal capital markets in multinational banking contribute to the transmission of financial shocks from parent banks to foreign subsidiaries. We find that internal capital markets transmit favorable and adverse shocks by affecting subsidiaries’ reliance on their own internal funds for lending. We also find that the transmission of financial shocks varies across types of shocks; is strongest among subsidiaries in Central and Eastern Europe, followed by Asia and Latin America; is global rather than regional; and becomes more conspicuous in recent years. We also explore various conditions under which the international transmission of financial shocks via internal capital markets in multinational banking is stronger, including the subsidiaries’ reliance on funds from their parent bank, the subsidiaries’ entry mode, and the capital account openness and banking market structure in host countries.     

International innovation and strategic initiatives: A research agenda

Despite the argument that leveraging the expertise of foreign subsidiaries to the global firm benefits the whole firm's competitive advantage, in the case of international innovation, such leveraging rarely takes place. We investigate this paradox, applying research on strategic initiatives to the context of international R&D. Developing a conceptual model on the basis of communication psychology, we analyse how the innovative expertise of R&D subsidiaries may be leveraged to benefit the global firm. Specifically, we determine six elements whose greater exploration can lead to a deeper understanding of how the innovation expertise of a foreign R&D subsidiary may be leveraged.     

Agency costs,governance, and organizational forms: Evidence from the mutual fund industry

Using a comprehensive sample of mutual funds and fund families for the period 1992–2004, this study examines the impact of fund management companies’ organizational forms on the level of agency costs within mutual funds. We find that, all else being equal: (1) funds managed by public fund families charge higher fees than those managed by private fund families; (2) public fund families acquire more funds than private fund families; and (3) funds of public fund families significantly underperform funds of private fund families. Collectively, these findings suggest that agency costs are higher in mutual funds managed by public fund families. Our results are consistent with the idea that the agency conflict between the fund management company and fund shareholders is more acute for public management companies because of their shorter-term focus.     

How the Subprime Crisis went global: Evidence from bank credit default swap spreads

How did the Subprime Crisis, a problem in a small corner of U.S. financial markets, affect the entire global banking system? To shed light on this question we use principal components analysis to identify common factors in the movement of banks' credit default swap spreads. We find that fortunes of international banks rise and fall together even in normal times along with short-term global economic prospects. But the importance of common factors rose steadily to exceptional levels from the outbreak of the Subprime Crisis to past the rescue of Bear Stearns, reflecting a diffuse sense that funding and credit risk was increasing. Following the failure of Lehman Brothers, the interdependencies briefly increased to a new high, before they fell back to the pre-Lehman elevated levels – but now they more clearly reflected heightened funding and counterparty risk. After Lehman's failure, the prospect of global recession became imminent, auguring the further deterioration of banks' loan portfolios. At this point the entire global financial system had become infected.     

Competition and innovation: Evidence from financial services

This paper presents new evidence on the relationship between competition and innovation by extending previous literature from manufacturing to financial services. We introduce a new measure of overall innovation by estimating and enveloping annual minimum cost frontiers to create a global frontier. The distance to the global frontier constitutes each bank’s technology gap, which decreases if the bank manages to innovate. Our innovation measure enables us to derive and estimate the model of Aghion et al. (2005b) at the firm level for the US banking industry. Based on individual bank Call Report data for the period 1984–2004, consistent with theoretical and empirical work by Aghion et al., we find evidence of an inverted-U relationship between competition and innovation that is robust over several different specifications. Further evidence on major structural changes in the US banking industry indicates that banks moved beyond their optimal innovation level and that interstate banking deregulation resulted in lower bank innovation. Policy implications to financial reform and prudential regulation are discussed also.     

Capital structure choice and company taxation: A meta-study

This paper provides a quantitative review of the empirical literature on the tax impact on corporate debt financing. Synthesizing the evidence from 48 previous studies, we find that this impact is substantial. In particular, the tax rate proxy determines the outcome of primary analyses. Measures like the simulated marginal tax rate (Graham, 1996) avoid a downward bias in estimates for the debt response to tax. Moreover, econometric specifications and the set of control-variables affect tax effects. Accounting for misspecification biases by means of meta-regressions, we predict a marginal tax effect on the debt ratio of about 0.27.     

R&D Intensity and Corporate Financial Policy: Some International Evidence

This paper presents evidence on the financial policies of firms strongly engaged in research and development activities. By referring to the under-investment paradox, the asset substitution problem, the asset specificity proposition and the information asymmetry literature, we postulate that R&D-intensive firms should adopt specific financial policies. In conformity with our hypotheses, empirical results based on a sample of R&D-intensive and non-R&D firms in four major industrialized countries (Europe, the UK, Japan and the US) show that R&D-intensive firms exhibit significant lower debt and dividend payment levels, but shorter debt maturities and higher cash levels than non-R&D ones.     

Realizing the volatility impacts of sovereign credit ratings information on equity and currency markets: Evidence from the Asian Financial Crisis

We examine the effects of different types of sovereign rating announcements on realized stock and currency market volatilities and cross-asset correlations around periods of financial crises. Using intraday market data and sovereign ratings data for nine sample countries in the Asia-Pacific region over 1997–2001, we find that currency and stock markets react somewhat heterogeneously to various rating announcements and that stock markets are more responsive to rating news than currency markets. We find new evidence that ratings events have significant and asymmetric impacts on intraday market data and that national market attributes influence rating impacts during financial crises.     

Mean reversion in long-horizon real exchange rates: Evidence from Latin America

This paper examines mean reversion in real effective exchange rates in six leading Latin American economies during the XXth century using a new data set. A unit-root approach is complemented by an error-correction model including key fundamentals such as terms of trade, trade openness and relative productivities. Unit-root testing shows a very slow process of reversion – if any – to a constant mean in the original series, rejecting the strict PPP hypothesis; however, mean reversion is found after allowing for trends and structural breaks with a half-life average of 1½ years for the six countries. We also found reversion to a conditional mean defined by the co-integrating relationship with an average half-life of 2½ years. Our estimates, although lower than the 3–5 year range that motivated the Rogoff’s puzzle, still indicate the presence of important obstacles to the adjustment process that need further investigation.     

The Performance of the Foreign‐Owned Sector of UK Manufacturing: Some Evidence and Implications for UK Inward Investment Policy

This paper analyses the reported performance of foreign‐owned manufacturing subsidiaries in the UK between 1994 and 1998. The paper is set in the context of uncertainty about the performance of some foreign‐owned sectors of UK manufacturing and the implications of this performance for the beneficial spillover effects sought by policy‐makers from foreign‐owned capital. Japanese‐owned subsidiaries are the focus of particular attention, with reported profits and tax liabilities significantly below those of subsidiaries from other national sources. The wider ramifications of this finding are analysed for the UK case, particularly in terms of the need to take into account the wider exchequer effects of inward investment in the general evaluation of the financial assistance provided to foreign firms.     

Financial market development and the effectiveness of R&D investment: Evidence from developed and emerging countries

Does financial market development enhance the effectiveness of R&D investment in an economy? To address this question, we apply three distinct approaches including (i) ordinary least square method, (ii) cross-country instrumental variable regression approach, and (iii) panel regression method. By using a dataset of both developed and emerging countries, we find that financial market development significantly contributes to the effectiveness of total R&D investment. This finding remains robust across different model specifications and individual estimation methods. Our finding provides an important guidance to policy makers in implementing a sound financial environment that can facilitate the total contribution of R&D investment.     

Using survey data to resolve the exchange risk exposure puzzle: Evidence from U.S. multinational firms

This paper examines the effect of unexpected exchange rate movements on U.S. shareholder wealth. Empirical results based on a sample of 634 U.S. multinational firms (1) confirm previously reported evidence that the disaggregation of the worldwide trade-weighted U.S. dollar exchange rate index into seven region-specific trade-weighted indices increases the precision and significance of exposure estimates; (2) show that models assuming that changes in spot exchange rates are unanticipated are frequently misspecified and, thus, unable to correctly detect the impact of currency movements on firm value; (3) reveal that forward and survey expectations enable us to distinguish between the effect of ‘realized’ and ‘unexpected’ currency movements; and (4) reveal that investors making pricing and hedging decisions prefer to use the information contained in short-term forward and survey expectation rates to the information included in long-term forecasts.
