Estimating a class of triangular simultaneous equations models without exclusion restrictions

This paper provides a control function estimator to adjust for endogeneity in the triangular simultaneous equations model where there are no available exclusion restrictions to generate suitable instruments. Our approach is to exploit the dependence of the errors on exogenous variables (e.g. heteroscedasticity) to adjust the conventional control function estimator. The form of the error dependence on the exogenous variables is subject to restrictions, but is not parametrically specified. In addition to providing the estimator and deriving its large-sample properties, we present simulation evidence which indicates the estimator works well.     

Estimation with overidentifying inequality moment conditions

This paper derives limit distributions of empirical likelihood estimators for models in which inequality moment conditions provide overidentifying information. We show that the use of this information leads to a reduction of the asymptotic mean-squared estimation error and propose asymptotically uniformly valid tests and confidence sets for the parameters of interest. While inequality moment conditions arise in many important economic models, we use a dynamic macroeconomic model as a data generating process and illustrate our methods with instrumental variable estimators of monetary policy rules. The results obtained in this paper extend to conventional GMM estimators.     

Second‐gift behaviour of first‐time donors to charity: an empirical study

• This study examined the second‐time charity giving behaviour of a sample of 551 young people during a 2‐year period following the occurrence of their first ever significant donation. It explored the factors that encouraged an individual to make a second gift, the probabilities that a donation would be made within certain time intervals after the initial gift (3 months, 6 months, a year, etc.) and the variables that influenced whether the second donation would go to the charity receiving the person's first gift or to a different charity. Relevant issues were investigated via a Cox proportional hazards regression analysis and through a binary logistic regression. Covariates employed in the course of the study included the degree of emotional uplift a person experienced and the level of mind‐set change that took place consequent to a first donation, donor confusion with the range and variety of charities available and the reputation and image congruity of the second charity to which the participant had contributed. The roles of personal inertia and social pressure when making donation decisions were also examined.

Assessing whether corporate social responsibility influence corporate value

This study used the corporate social responsibility (CSR) index to gauge the corporate value and social responsibility performance of corporations in Taiwan. We investigated whether CSR influences corporate value and whether the extent of that influence varies with corporate value or time. The results indicate that the influence of CSR on corporate value does not change with time. CSR exerts a positive influence on company value, and this influence does not change over time. However, the extent of the influence significantly varies with corporate value. When the corporate value of a company is not high, investing in CSR would only increase costs and fail to effectively increase corporate value. In contrast, if the corporate value of the company is high, investments in CSR in this circumstance would instead promote the effective increase of corporate value.     

Displaced lognormal volatility skews: analysis and applications to stochastic volatility simulations

We analyze the implied volatility skews generated by displaced lognormal diffusions. In particular, we prove the global monotonicity of implied volatility, and an at-the-money bound on the steepness of downward volatility skews, under displaced lognormal dynamics, which therefore cannot reproduce some features observed in equity markets. A variant, the displaced anti-lognormal, overcomes the steepness constraint, but its state space is bounded above and unbounded below. In light of these limitations on what features the displaced (anti-)lognormal (DL) can model, we exploit the DL, not as a model, but as a control variate, to reduce variance in Monte Carlo simulations of the CEV and SABR local/stochastic volatility models. For either use—as model, or as control variate—the DL’s parameters require estimation. We find an explicit formula for the DL’s short-expiry limiting volatility skew, which allows direct calibration of its parameters to volatility skews implied by market data or by other models.     

Delegated trading and the speed of adjustment in security prices

Institutional trading arrangements often involve the portfolio manager delegating the task of trade execution to a separate division within the firm. We model the agency conflict that arises in this setting and show that optimal performance benchmarks often create an incentive to execute orders contrary to concurrent information flow. We hypothesize that aggregate contrarian trading resulting from widespread application of such benchmarks leads to delays in the assimilation of information in security prices. Using institutional trading data, we document the hypothesized contrarian trading pattern and relate the pattern to price-adjustment delays in the response of individual stocks to index futures returns. The evidence supports the assertion that delegated institutional trading contributes to these delays.     

Business Cases and Corporate Engagement with Sustainability: Differentiating Ethical Motivations

This paper explores links between different ethical motivations and kinds of corporate social responsibility (CSR) activities to distinguish between different types of business cases with regard to sustainability. The design of CSR and corporate sustainability can be based on different ethical foundations and motivations. This paper draws on the framework of Roberts (Organization 10:249–265, 2003) which distinguishes four different ethical management versions of CSR. The first two ethical motivations are driven either by a reactionary concern for the short-term financial interests of the business, or reputational, driven by a narcissistic concern to protect the firm’s image. The third responsible motivation works from the inside-out and seeks to embed social and environmental concerns within the firm’s performance management systems, and the fourth, a collaborative motivation, works to bring the outside in and seeks to go beyond the boundaries of the firm to create a dialogue with those who are vulnerable to the unintended consequences of corporate conduct. Management activities based on these different ethical motivations to CSR and sustainability result in different operational activities for corporations working towards sustainability and thus have very different effects on how the company’s economic performance is influenced. Assuming that corporate managers are concerned about creating business cases for their companies to survive and prosper in the long term, this paper raises the question of how different ethical motivations for designing CSR and corporate sustainability relate to the creation of different business cases. The paper concludes by distinguishing four different kinds of business cases with regard to sustainability: reactionary and reputational business cases of sustainability, and responsible and collaborative business cases for sustainability.     

Corporate ownership and the theory of the multinational enterprise

This paper makes a contribution to the theory of the multinational enterprise (MNE) and, in particular, to why firms undertake foreign direct investment (FDI) rather than alternative strategies. We argue that FDI and its strategic alternatives involve different patterns of costs and returns over time, and hence different levels of risk and uncertainty. Traditional theories of the MNE conceptualize the firm as a risk-neutral decision-making entity with short-term efficiency objectives, and hence do not take these issues into account. This may be reasonable for firms with passive professional managers and widely-dispersed shareholders, operating in countries with the Anglo-American system of corporate governance. But many firms operate under quite different systems of corporate governance where concentrated shareholdings are commonplace and markets for corporate control are weak or non-existent. In these cases, shareholders exert considerable influence on all aspects of firm strategy including FDI. Furthermore, different groups of shareholders (State, family, institutions) are likely to have different objectives, different attitudes towards risk, and different decision-making time horizons. We thus suggest that the traditional theories of the MNE need to be extended to embrace consideration of corporate ownership (and other governance dimensions).     

The export performance of emerging economy firms: The influence of firm capabilities and institutional environments

We advance a two-stage theoretical model which contends that the export performance of emerging economy firms (EEFs) will depend both upon their firm-specific capabilities and their home institutional environments. Specifically, we argue that EEFs will be more likely to export when facing more uncertainty at home from greater political instability, substantial informal competition, and high corruption. Furthermore, we hypothesize that firms’ export intensities will be contingent upon specialized internal capabilities such as a skilled workforce, top managerial experience, and access to external technologies. We test these hypotheses using a dataset of more than 16,000 firms from the four BRIC economies (i.e., Brazil, Russia, China and India). Our results confirm that political instability and informal competition have robust effects on the export propensity of EEFs, whilst export intensity is contingent upon the availability of skilled workers and access to external technologies via licensing.
