Effects of Knowledge Spillovers on Knowledge Production and Productivity Growth in Korean Manufacturing Firms

Using Korean firm‐level data, this paper studies the effects of knowledge spillovers on knowledge production and productivity growth. Data from 213 Korean firms for the years 1985 to 2007 are used, and the number of patent applications is used as a proxy variable for knowledge. The results show that all the growth rates of output, patents, and productivity are higher in high‐technology firms. Regression results show that the spillover effect on knowledge production and productivity growth is very significant, and that the spillover effect is larger in small firms than in large firms. Moreover, spillover effects on productivity growth are larger after 1995, when Korean intellectual property rights were strengthened. Our findings suggest that the effects of knowledge spillover on productivity are positively correlated with strong intellectual property rights.     

The Impact of Industry Characteristics and IPR Policy on Foreign Direct Investment

This paper investigates the interaction of industry characteristics and intellectual property rights (IPRs) on multinational firm behavior. The results suggest that firms in industries with high capital costs are more likely to maintain control over production knowledge in countries with less intellectual property protection by engaging in foreign direct investment (FDI). Moreover, when IPRs are strong, firms in industries with high investment in research and development (R&D) are more likely to enter a market by licensing to an unaffiliated host firm. JEL no.

Why Do Large Firms' Prices Anticipate Earnings Earlier than Small Firms' Prices?*

This paper presents evidence that the positive association between firm size and price leads of earnings is not solely a function of private search incentives for firm‐specific information. Specifically, we find that small‐firm prices also lag large‐firm prices with respect to industry‐wide information. Our empirical analysis extends Collins, Kothari, and Rayburn 1987 and Freeman 1987, who document that security‐price leads of earnings are positively associated with market capitalization. In particular, we examine the association between firm size and the timing of security returns for two components of annual earnings changes: the average change for a firm's industry and the firm's idiosyncratic change. We find that large firms' prices have a longer lead than small firms' prices with respect to both components. Large firms' early lead on industry‐wide earnings suggests that returns of large firms predict returns of same‐industry small firms. To test this implication, we construct a portfolio of long (short) positions in small firms when the prior month's returns of large firms in their industry are above (below) average for large firms in other industries. This zero investment portfolio earns 4.5 percent over 12 months.     

Information Conveyed in Announcements of Analyst Coverage*

This paper examines the security market response to the announcement of sell-side analysts' decisions to initiate coverage of a firm. We examine the market reaction to the initiation announcement and the accompanying investment recommendation, by disaggregating our sample based on existing analyst coverage at the announcement date. We find, on average, a significantly larger, positive stock price reaction to buy recommendations conveyed in announcements of coverage initiation for firms with a small existing analyst following compared to such announcements for firms receiving no prior analyst coverage. Tests show that the relation between the extent of preexisting analyst coverage and market response is nonlinear and concave down in shape. Specifically we find that lightly followed firms, on average, experience larger price reactions to announcements of coverage initiations than either previously uncovered firms or more heavily followed firms. We test for and find that this result holds over a range of definitions of light coverage and is not attributable to the presence of an underwriting relationship existing between the analyst's employer and the firm receiving coverage. We do find that initiations by analysts named to Institutional Investor magazine's “All-American Research Team” produce a significantly larger market reaction than do initiations by non-All-American security analysts. In addition, similar to the market response associated with other types of information events, we observe that proxies for the richness of the initiated firms' preannouncement information environment are associated with event-day average abnormal returns.     

Listing and financial constraints

We confirm, with a twist, that listing to a stock exchange can mitigate financial constraints of firms, using Japanese firm-level data of 20 years, 1995–2014, controlling for the main-bank relationship and majority owner influence. Compared to a similar unlisted firm, a listed firm has a lower marginal product of capital on average and more new borrowings during recessions. Theoretically, we argue that these are the key pieces of evidence that indicate less tight financial constraints for the listed firms than the unlisted firms. However, the listed firms do not borrow more on average over time. They rather maintain a lower leverage so that they can mitigate the borrowing constraints. We also find that the listed firms do not face lower interest rates.     

The impact of foreign direct investment in China on employment adjustments in Taiwan: Evidence from matched employer–employee data

Using a unique matched employer–employee dataset on Taiwanese manufacturing, we examine the impact of foreign direct investment in China on domestic employment adjustments controlling for firm and worker heterogeneity as well as for potential endogeneity of firms’ expansion in China. Our findings suggest that workers employed at firms with higher levels of investment in China are more likely to leave the firm, compared with workers at firms with zero or lower levels of investment in China. We provide evidence that foreign expansion in China decreases worker employment security at parent companies, particularly for low-skilled workers. Employment adjustments through employer-to-employer transitions are found to be highly associated with wage losses, with the strongest wage effects for low-skilled workers who shift employment between industries. Moreover, we find no evidence that FDI in China contributes to skill upgrading at parent companies.     

Are Older Workers Harmful for Firm Productivity?

This paper investigates the effects of the workforce age structure on the productivity of large Belgian firms. More precisely, it examines different scenarios of changes in the proportion of young (16–29 years), middle-aged (30–49 years) and older (more than 49 years) workers and their expected effects on firm productivity. Using detailed matched employer–employee data, we find that young workers are significantly more productive than older workers. Yet, results also show that age structure effects on productivity: (i) have substantially decreased over time and (ii) are much stronger in ICT than in non-ICT firms.     

Monetary policy,cash holding and corporate investment: Evidence from China

This paper uses 13,766 firm-year observations between 2003 and 2013 from China to investigate the effects of monetary policy on corporate investment and the mitigating effects of cash holding. We find that tightening monetary policy reduces corporate investment while cash holdings mitigate such adverse effects. The cash mitigating role is especially significant for financially constrained firms, non-state-owned enterprises (non-SOEs) and those firms located in a less developed financial market. Cash holding also improves investment efficiency when monetary policy is tightening and tightening monetary policy enhances the ‘cash-cash flow’ sensitivity. Our empirical evidence calls for a critical evaluation on the monetary policies implemented in China which are less effective for state-owned enterprises. It also calls for a necessity for local government to further develop regional financial markets to protect vulnerable businesses, such as non-SOEs and financially constrained firms, from external shocks in order to maintain their sustainable growth and competitive advantages.     

Market Consequences of Earnings Management in Response to Security Regulations in China*

Under the 1996‐98 security regulations in China, the accounting rate of return on equity (ROE) has to be greater than 10 percent for three "consecutive" years for a firm to qualify for stock rights offers. Despite declining economic conditions during this period, the percentage of firms reporting ROE between 10 and 11 percent is about "three" times that for 1994‐95. This unique regulatory environment provides a natural experimental setting for the empirical assessment of earnings‐management behavior and its consequences. This study examines whether listed Chinese firms manage earnings to meet regulatory benchmarks and whether regulators and investors consider the quality of earnings in their respective regulatory and investment decisions. On the basis of a sample of listed Chinese firms from 1996 to 1998, we observe that managers execute transactions involving below‐the‐line items and use income‐increasing accounting accruals to meet regulatory ROE targets for stock rights offerings. The firms that apply for, but fail to receive, regulatory approval manage earnings more significantly than do firms that receive approval and pair‐matched control firms. Our market study also suggests that investors differentiate the quality of earnings and put less value on earnings suspected of a greater degree of management. Overall, our results imply that the regulatory bodies and investors to some extent make rational adjustments for the quality of earnings.     

Effects of presidents’ characteristics on internationalization of small and medium firms in Japan

Recent heterogeneous-firm models of international trade suggest that productivity determines whether firms engage in export activity and foreign direct investment. In practice, however, many productive firms are not internationalized, whereas many unproductive firms are, which suggests that there are factors other than productivity that influence firms’ internationalization. This study uses a unique panel data set for Japanese small and medium enterprises (SMEs) to examine whether the personal characteristics of a firm’s president are factors in firm internationalization. We find that SMEs with a risk-tolerant, forward-looking president are more likely to be internationalized. These effects are large in magnitude, as is the productivity effect, which provides a partial explanation as to why many productive firms are not internationalized. In addition, we find that productivity has an insignificant effect on firms exiting export markets, whereas presidential myopia increases the probability of exit. The evidence further suggests that a firm’s initial export costs become sunk following its entry into export markets, which explains why many unproductive firms are internationalized.     

Technology spillovers from Chinese outward direct investment: The case of Ethiopia

The present study uses firm survey data of 1033 manufacturing firms operating in Ethiopia in 2011 to examine the impact of Chinese outbound direct investment on the productivity of domestic firms. Particularly, we attempt to answer two questions. Firstly, are Chinese-owned (henceforth foreign) firms more productive than local ones? Secondly, does the presence of foreign firms generate technology spillovers on domestic firms operating in the same industry? Our empirical results show that foreign firms are more productive and that their presence has different spillover effects on the productivity of domestic firms. In particular, we find that domestic firms with higher absorptive capacity experience positive spillovers, while those with low absorptive capacity witness negative spillover. We also find that small firms and non-exporting firms benefit more from spillovers than do other types of domestic firms. In this study, instrumental variables are used to address the potential endogeneity between foreign firm presence and domestic firm productivity.     

Compensation negotiation and corporate governance: the evidence from China

This paper examines CEO pay dispersion for the listed companies in China. We apply a two-tier stochastic frontier model to the CEO compensation framework where asymmetric information generates a surplus between the minimum wage that CEOs accept and the maximum payment that firms offer. This surplus leads to CEO pay dispersion coming from the negotiation power between the CEO and the firm. We generate the surplus extracted by each CEO-firm pair and analyze how corporate governance affects them. An empirical analysis finds that: (1) On average, CEOs are paid 23.26% more than the benchmark; (2) additionally, we examine the bargaining power in state-owned enterprises (SOEs) and non-state-owned enterprises (non-SOEs). We find that CEOs in SOEs have less bargaining power due to compensation regulations. We then examine compensation for new CEOs hired externally and find that CEOs hired externally have less bargaining power on average; and (3) corporate governance has a significant effect on the salary bargaining power of each agent. More specifically, the CEO-Chairman dummy has a significant positive effect on the bargaining power of firms and CEOs, but the latter is larger. Board size has a negative effect on both. Independent directors help improve the bargaining power of the firms and board meeting times help enhance the bargaining power of the CEOs. Equity concentration has a significant negative effect on both sides.     

How Quickly Do Firms Adjust to Optimal Levels of Tax Avoidance?

The trade‐off literature asserts that managers weigh the direct benefits of tax avoidance against the associated nontax costs. This literature implies each firm has a unique optimal level of tax avoidance that balances these costs and benefits. Our study is the first to document how quickly the average firm moves toward its optimal level of tax avoidance. We find that the typical firm converges toward its optimum at a rate that ranges from approximately 69 to 84 percent over a three‐year period, depending upon model specifications. Consistent with asymmetric levels of frictions across the tax avoidance distribution, we find the speed of adjustment is greater for firms below their optimal level of tax avoidance than for firms above. We perform additional cross‐sectional analyses to provide insight into some of the frictions that prevent firms from adjusting completely to their optimal level of tax avoidance. We generally find growth firms exhibit slower adjustment speeds and provide limited evidence that both multinational firms and income‐mobile firms exhibit faster adjustment speeds.     

Equity Valuation Effects of the Pension Protection Act of 2006*

We investigate the equity valuation effects of the Pension Protection Act of 2006 (PPA 2006). The PPA 2006 has two main provisions: (1) firms must fully fund their pension plans within seven years (previously allowed 30 years to fund 90 percent of the pension liability) and (2) firms receive a tax deduction for contributions up to 150 percent of the pension liability (previously 100 percent). After controlling for the effects of SFAS 158, growth opportunities, the cost of external funds, and other information released during our sample period, we examine pension firms’ abnormal returns surrounding key dates in the legislative process leading to the adoption of the PPA 2006. First, we find a mean negative abnormal return of ?4.20 percent during the period in which the PPA 2006 was first voted on by Congress. The mean (median) firm in our sample experienced a $310 million ($60 million) decline in market capitalization. Second, we find that the valuation effect was more negative for firms with larger unfunded pension liabilities and larger capital expenditure requirements, while firms with higher marginal tax rates experienced a positive effect. Third, we find no evidence of differential valuation effects for firms in different “at risk” categories as defined by the PPA 2006. Finally, we find a significant number of pension freezes occurred during our sample period. Our results are stronger when excluding these firms from our sample.     

Conditional Conservatism and Debt versus Equity Financing

Extant research suggests that conditional conservatism reduces information asymmetry between a firm and its shareholders as well as its debtholders. However, there is little evidence on whether conditional conservatism reduces information asymmetry differentially for shareholders and debtholders. We use the setting of a firm's choice between equity versus debt when it seeks a significant amount of external financing to examine this research question. We find that when firms raise a significant amount of external financing, the use of equity (versus debt) increases with the level of conservatism. We also find that the reduction in cost of equity associated with conservatism is greater for equity issuers than for debt issuers, but find no such difference when we examine cost of debt. In addition, we find that the positive effect of conservatism on the choice of equity issuance (versus debt issuance) is accentuated when the information asymmetry between the firm and its shareholders is more severe. Overall, our results suggest that conservatism reduces information asymmetry more between firms and shareholders than between firms and debtholders.

Short-term loans and Firms' high-quality innovation: Evidence from the access to patent-backed loans in China

When obtaining short-term loans, an innovative firm tends to expand its production scale, thereby reallocating its R&D-related resources away from innovation. By exploiting the unique situation in China that patenting firms for the first time obtained short-term patent-backed loans (PBLs), we find that the PBL access negatively influences firms' propensities of producing high-quality innovation. Consistent with the R&D resource reallocation hypothesis, we find that this negative effect exists only among firms initially having invention patents; it is more pronounced when the PBL covers a larger portion of firm investment and when these firms expand more aggressively. We confirm the scale expansion effect by finding that the PBL access positively influences firms' subsequent size.     

Trade liberalization and wage inequality: Evidence from Korea

This paper investigates the heterogeneous income distribution effects of trade liberalization using Korean survey data from years of 2000–2015. Following the Stolper-Samuelson theorem most of previous research studying the effects of trade liberalization on wage differences focus on workers’ characteristics (e.g., skilled or unskilled) while heterogeneity within the same worker group has not been yet substantially investigated. To fill this gap, this paper provides empirical evidence of wage inequality across firms within the same group of workers caused by trade liberalization, potentially implied in the new-new trade models with firm heterogeneity. Employing a difference-in-differences (DID) specification, we find that the wages of unskilled workers in Korea have increased since its FTAs with more advanced countries, such as members of EU and the US, came into effect, while the effects on the wages of skilled workers are negative but not statistically significant. We also show that wage effects are heterogeneous across firms within unskilled and skilled worker groups, while the positive effects are statistically significant and largest for unskilled workers in medium-large sized firms. These findings are in line with both traditional and new-new trade models.     

Higher productivity in importing German manufacturing firms: self-selection, learning from importing, or both?

This paper uses a newly available comprehensive panel data set for manufacturing enterprises from 2001 to 2005 to document the first empirical results on the relationship between imports and productivity for Germany, a leading actor on the world market for goods. Furthermore, for the first time the direction of causality in this relationship is investigated systematically by testing for self-selection of more productive firms into importing, and for productivity-enhancing effects of imports (‘learning-by-importing’). We find a positive link between importing and productivity. From an empirical model with fixed enterprise effects that controls for firm size, industry, and unobservable firm heterogeneity we see that the premia for trading internationally are about the same in West and East Germany. Compared to firms that do not trade at all two-way traders do have the highest premia, followed by firms that only export, while firms that only import have the smallest estimated premia. We find evidence for a positive impact of productivity on importing, pointing to self-selection of more productive enterprises into imports, but no clear evidence for the effect of importing on productivity due to learning-by-importing.     

Economic policy uncertainty and firm’s cash holding in China: The key role of asset reversibility

This paper investigates how asset reversibility affects the sensitivity of firm’s cash holding to economic policy uncertainty in China. Using the 2012 national input-output table for 139 industries, we measure the industry-level asset reversibility and match them with nonfinancial publicly listed firms over 2007−2017. The results show that asset reversibility has a significant and negative effect on the positive uncertainty-cash holding sensitivity, especially for firms with more severe financial constraints. Furthermore, we find that firms with higher asset reversibility invest more in fixed assets, suggesting that real investment is an important mechanism. In addition, baseline results are robust to potential endogeneity and alternative measures of asset reversibility and economic policy uncertainty. Our findings reveal that asset market friction is a critical determinant of firm’s cash holding.
