Has SOX Enhanced Non–Big 4 Auditors' Ability to Deal with Client Pressure?

We investigate whether non–Big 4 auditors have enhanced their ability to resist client pressure over accrual reporting following the Sarbanes‐Oxley Act (SOX). Regressing abnormal accruals on proxies for economic bonding, we find that changes in the association, defined as (Post–Pre), are significantly negative, implying an improvement in auditor independence after SOX. Among non–Big 4 auditors, only Tier 3 auditors compromised reporting objectivity before SOX, but neither Tier 2 nor Tier 3 auditors yielded to client pressure after SOX. Evidence that these two groups of non–Big 4 auditors differ in the way they cope with client pressure in a loose regulatory regime highlights the importance of assessing the efficacy of SOX separately for subsets of auditors and contributes to an understanding of the underresearched, but inherently important, segment of the audit market served by non–Big 4 auditors. Further analysis indicates that the low pre‐SOX audit quality observed in the full sample is driven by non–PCAOB registrants.     

The influence of reputation on supplier selection: An empirical study of the European automotive industry

Using an original database, integrated with information by the web, we propose an ex-post analysis on the main factors influencing the selection process of tier 1 suppliers in the automotive industry. There is plenty of literature on how buyers should select their suppliers, but the literature on how they really do so is scarce. We contribute analysing an original database collecting purchasing contracts information within the automotive components market in Europe. We investigate, through different econometric approaches the influence of traditional supplier selection criteria in combination with different reputation factors. Our findings suggest that reputation plays a crucial role more than classical criteria; in particular, suppliers, which serve a diversified customer portfolio or with strong exposure to premium brand customers have better chances to gain additional orders and broaden their customer base even more. The latter means that OEMs have to increase their reputation in order to be more attractive for suppliers.     

Is high-frequency trading tiering the financial markets?

Some academic research has identified the possibility of High-Frequency Trading (HFT) creating a two tier market, in which the fast traders mostly deal with each other at most favourable prices and spread, leaving the slower investors to share the least profitable deals. Yet, although intriguing, this view has been seldom quantitatively investigated − and that is the gap found in previous research. A computer simulation has been produced to mimic the behaviour of both slow and fast traders, each category showing characteristics consistent with their behaviour on the markets. In particular, High-Frequency (HF) traders show their preference for aggressive orders when the bid-ask spread is tight and are less aggressive when spread is wide. The Low-Frequency (LF) traders are then forced to live with the remaining deals, hoping to profit from longer term price movements. The purpose of this piece of research is to verify whether HF traders (HFTs) tend to deal with each other and, something not investigated by previous studies, if LF traders also mainly restrict their trading with other slow traders.The results show some tendency toward markets actually splitting into two-tiers: they confirm previous findings of HF traders' tendency to deal with their similar counterparts in case of thin bid-ask spread (which means higher probability of profits for the aggressive side), leaving mostly LF traders to deal amongst themselves when the spread is wider, so aiming at long-term gain (which makes trading inherently riskier).     

The impact of buyer–supplier relationships on supplier innovativeness: An empirical study in cross-border supply networks

Drawing on organizational learning and the relational view of the firm, this study seeks to understand the factors that drive supplier innovativeness in the context of cross-border supply relationships. To address this research objective, a survey included 189 parts and components manufacturers (suppliers) in Turkey; hierarchical regression analysis is used to test the hypotheses. The findings demonstrate that interfirm knowledge sharing routines, relation-specific investments, and governance mechanisms may promote supplier innovativeness by expanding the supplier's knowledge resources and encouraging it to invest in innovative activities. In addition, this research emphasizes differentiating effects of the supplier's tier position for the impacts of buyer assistance and cooperative tie. As such, this study contributes to the purchasing and supply management literature by empirically showing how buyer–supplier relationships, particularly in cross-border supply networks, affect supplier innovativeness.     

Capital regulation and bank risk‐taking – new global evidence

This study investigates the link between capital regulation and bank risk‐taking. Using a sample of over 1,800 banks in 135 countries, I find that the relationship between capital regulation and bank risk‐taking (measured by z‐score) is an inverse ‘U’ shape. That is, as capital ratios increase, a bank will take less risk initially, then more risk. These results are robust to numerous additional tests, including estimation methods. I also find that more stringent regulations mitigate the effect of higher capital on lowering bank risk‐taking. Increased capital requirements, even when risk‐based, induce risk‐taking at higher levels, irrespective of whether banks are well‐ or under‐capitalised.     

Estimating the size of the Chinese outbound travel market: A demand-side approach

The Chinese outbound travel market has been one of the fastest-growing international markets over the past decade. However, estimating the size and identifying key tourist-generating areas for the Chinese travel market remain a significant challenge for international marketers. This empirical study employs an incidental target-market approach and presents updated research findings concerning this burgeoning market. Primary and secondary tourist-generating cities of Mainland China were identified based on population size and level of socioeconomic development, and their market potential for outbound travel was assessed through a large-scale telephone survey. This study estimated that the current Chinese outbound travel market comprises approximately 22 million city residents, among whom 11.5 million have traveled or plan to travel to destinations outside Asia. In addition to estimating market size and making recommendations on target cities, the study also introduces an effective research design for identifying target markets and customers.
