Option implied volatilities and the cost of issuing equity

The structure of a firm-commitment Seasoned Equity Offering (SEO) resembles a put-option underwritten by an investment bank syndicate (Smith, 1977). Employing implied volatilities from issuers’ stock options as a direct forward-looking measure, this paper examines the impact of expected price risk around SEO issue dates on the direct cost of issuing equity. Using a comprehensive sample of 1208 SEOs between 1996 and 2009, we find issuers with higher option implied volatilities raise less external equity capital and pay higher investment bank fees in the stock market, ceteris paribus. The effect of implied volatility on the investment bank fees is stronger for larger issuers with lower pre-SEO abnormal realized stock volatilities, and for SEOs with higher expected price pressures around issue dates. These relationships are robust to adjustments for correlations among control variables, sample selection bias and also simultaneous determination of offer size and SEO fees.     

Inconvenience cost of mobile communication failure: The case of South Korea

Mobile communication failure can occur when mobile traffic exceeds the manageable level. This depends on frequency bandwidth. Mobile communication failure causes inconveniences in a user's daily life that lead to social and economic damage. To address this issue, mobile telecommunications companies deploy additional bandwidths and develop new technologies, but these are costly strategies. This study applies a spike model based on a contingent valuation method (CVM) to measure the inconvenience cost resulting from mobile communication failure. The mean monthly willingness-to-pay (WTP) to avoid communication failure per user is estimated to be KRW 898.14 (USD 0.80) over a period of five years in our study. The inconvenience cost borne by the population is estimated to be KRW 2.97 trillion (USD 2.61 billion). Users experiencing greater frequency of communication failure are found to be willing to pay more to avoid the inconvenience. When excluding respondents citing zero-WTP, the mean WTP per user was calculated to be KRW 3426.41 (USD 3.01). Data traffic usage and frequency at which communication failure is experienced are variables that exhibit statistically significant effects on WTP to avoid mobile communication failure. Overall, estimation results show that a price discrimination based on data traffic usage or quality can be considered by mobile telecommunications companies and regulators to address the issue of data traffic inducing mobile communication failure.     

Banks’ Governance and Innovation: Evidence from the Listed Firms in China

ABSTRACT

The article investigates the relationship between banks, agency costs, and innovation ability of listed firms. The role of banks in affecting innovation is a very important topic especially in China where banks play more important roles than equity markets. We find that banks providing short-term funds to listed non-high-tech firms dampen their innovation ability significantly. However, the relationship between short-term loans and innovation ability in high-tech firms is insignificant. The effects of short-term loans on innovation ability are significantly different between high-tech and non-high-tech firms. Further examination shows that high-tech firms with more short-term bank loans have significantly less abnormal management expenses than non-high-tech firms in the next year. The reduced abnormal management expenses in the next year significantly enhance the innovation ability in the year after next.     

Sustainability marketing at the farmers’ market: An ethnographic analysis of ambiguous communication

Farmers’ markets have grown rapidly in recent decades. One explanation for this growth relates to consumers’ view that farmers’ market products are more sustainable. While many have analyzed customer preferences at farmers’ markets, few have examined farmers’ message strategies in this space. Little has been done to analyze the ways farmers use sustainability as a marketing approach. This ethnographic research is based on 100 hr of observation and in‐depth interviews with 36 participants and analyzes the ways farmers position their products as sustainable to customers. The findings indicate that sustainability is not a primary topic of conversation during customerfarmer interaction. However, related concepts such as environment, local, organic, and chemical serve as the proxies for sustainability, even though these messages are presented ambiguously.     

Floating a “lifeboat”: The Banque de France and the crisis of 1889

When faced with a run on a “systemically important” but insolvent bank in 1889, the Banque de France pre-emptively organized a lifeboat to ensure that depositors were protected and an orderly liquidation could proceed. To protect the Banque from losses on its lifeboat loan, a guarantee syndicate was formed penalizing those who had participated in the copper speculation that had caused the crisis bringing the bank down. Creation of the syndicate and other actions were consistent with mitigating the moral hazard from such an intervention. This episode contrasts the advice given by Bagehot to the Bank of England to counter a panic by lending freely at a high rate on good collateral, allowing insolvent institutions to fail.     

The Neutrality Illusion: Biased Economics,Biased Training,and Biased Monetary Policy. Testing the Role of Ideology on FOMC Voting Behaviour

This research is trying to shed light on two myths that are usually widespread: the first one being the idea of the academic economist as a neutral scientist finding uncontestable consensual truths, thanks to uncontestable empirical methods, the second, the idea of the central banker as a Weberian neutral bureaucrat setting aside personal beliefs to act mechanically for the common good. Deconstructing this ‘neutrality illusion’, this work argues that economics is actually a divided and ideologically marked discipline despite its aim at natural-science-type-legitimacy. It argues in a related discussion that such ideological bias also impedes a purely neutral conduct of monetary policy, undermining the very idea of central bank independence. Linking these two arguments, it argues that graduate training in economics is the first place for the formation of biased preferences, because of the substantial ideological sorting that exists across universities. Using a unique database on FOMC members’ votes and ideology, the paper tests this idea empirically and despite unavoidable caveats, finds robust evidence of a systematic impact of the ideological features of their alma mater on FOMC members’ voting behaviour – impact that we found more important than the other traditional determinants of central bankers’ actions.     

General or central government? Empirical evidence on political cycles in budget composition using new data for OECD countries

Previous studies used general government data to examine whether national governments’ electoral motives and ideology influenced budget composition in OECD countries. General government data includes, however, the state and local level. Using new data for general and central government over the period 1995–2016, I reexamine political cycles in budget composition. The results suggest that, both at the general and central government level, leftwing governments spent more on education and less on public services than rightwing governments. Defense expenditure was somewhat lower under leftwing than rightwing governments and in election years; especially in federal states. Effects of government ideology on the individual expenditure categories are larger at the central than general government level. Scholars need to re-examine results on ideology-induced effects that have been derived from general government data where central government data should have been used.
