Price-volume relation in stocks: A multiple time series analysis on the Singapore market

We examine the price-volume relation in stocks using the multiple time series approach due to Tiao and Box (1981). This approach has the advantage of treating price and volume jointly and symmetrically (without enforcing the roles of input and output). It is free of the simultaneity bias in regression analysis and the unidirectional dynamics imposed by transfer function models. Empirical results show that there is implicit positive correlation between price and volume through their residuals. However, the results for the explicit lead and lag relations are mixed. The technical analysts' adage that volume often leads the trend of price is not supported. Nonetheless, the implicit relationship between price and volume confirms the usefulness of incorporating volume data to forecast future return. Our analysis shows that the multiple time series models outperform the univariate models in post-sample forecasts.     

The effect of financial constraints,investment policy,product market competition and corporate governance on the value of cash holdings

This study empirically investigates the value shareholders place on excess cash holdings and how shareholders’ valuation of cash holdings is associated with financial constraints, firm growth, cash‐flow uncertainty and product market competition for Australian firms from 1990 to 2007. Our results indicate that the marginal value of cash holdings to shareholders declines with larger cash holdings and higher leverage. However, firms that are more financially constrained, that have higher growth rates and that face greater uncertainty exhibit a higher marginal value of cash holdings. These findings are consistent with the explanation that excess cash holdings are not necessarily detrimental to firm value. Firms with costly external financing and that also save more cash for current operating and future investing needs find that the market values these cash hoarding policies favourably. Finally, there is limited evidence of an association between various corporate governance measures and the value of cash holdings for a shorter sample period.

Lessons from the field: reflecting on a tourism research journey around the ‘celtic’ periphery

The challenge within the tourism academy to acknowledge the situated nature of knowledge within the research process is intensifying. Drawing on a multidisciplinary body of reflexive narratives and recent work in tourism that acknowledges the personal influences that construct knowledges, this paper embraces this challenge by offering an autobiographic narration of field work in Ireland, Scotland and Cornwall. Food tourism is employed as a conceptual vehicle to pursue a more culturally focused, critical tourism investigation, thereby contributing to work that extends tourism research beyond the sphere of management and business. Drawing on research involving in-depth interviews with (food) tourists and participant observation, it is suggested that tourism knowledge is constructed at the micro-level, directly shaped by seemingly insignificant or overlooked moments. The paper illustrates how personal aspects of field work (gender, age, ethnicity, personal insecurity, loneliness and physical demands), combined with overcoming more practical issues (weather and transport logistics), should inform the contextual foundations of any empirical research; it from these moments where tourism knowledge is truly cultivated. Underpinned by qualitative methodological literature within a framework of critical realism, it urges others to embark upon a similar reflexive journey in order to develop tourism research into a robust sphere of academic enquiry.     

Mesenteric actinomycosis

We report a case of abdominal actinomycosis demonstrated on computed tomography (CT) as an isolated mesenteric mass with radiating linear and nodular densities. The lesion mimicked a mesenteric tumor with desmoplastic reaction. The clinical and radiological features of this uncommon entity are reviewed.     

A further analysis of the lead-lag relationship between the cash market and stock index futures market

The intraday lead-lag relation between returns of the MajorMarket cash index and returns of the Major Market Index futuresand S&P 500 futures is investigated. Empirical results showstrong evidence that the futures leads the cash index and weakevidence that the cash index leads the futures. The asymmetriclead-lag relation holds between the futures and all componentstocks, including. those that trade in almost every five-minuteinterval. Evidence indicates that when more stocks move together(market-wide information) the futures leads the cash index toa greater degree. This suggests that the futures market is themain source of market-wide information.     

The informativeness of domestic and foreign investors’ stock trades: Evidence from the perfectly segmented Chinese market

This paper uses the perfect market segmentation setting in China's stock market to compare the information content of the stock trades of domestic and foreign investors. We study 76 firms that issue both A-shares (for domestic investors) and B-shares (for foreign investors) and compare the price discovery role of the two segmented markets in China. Before Feb 19, 2001, the A-share market led the B-share market in price discovery, as the signed volume and quote revision of the A-share market had strong predictive ability for B-share quote returns, but not vice versa. After Feb 19, 2001, because some domestic investors were allowed to invest in the B-share market, we find evidence for a reverse causality from the B-share to the A-share market. Nevertheless, the [Hasbrouck (1995). One security, many markets: determining the contributions to price discovery, Journal of Finance 50, 1175–1199.] information share analysis reveals that A-shares continue to dominate the price discovery process.     

Pathways After Default: What Happens to Distressed Mortgage Borrowers and Their Homes?

We use a detailed dataset of seriously delinquent mortgages to examine the dynamic process of mortgage default—from initial delinquency and default to final resolution of the loan and disposition of the property. We estimate a two-stage competing risk hazard model to assess the factors associated with post-default outcomes, including whether a borrower receives a legal notice of foreclosure. In particular, we focus on a borrower’s ability to avoid a foreclosure auction by getting a modification, by refinancing the loan, or by selling the property. We find that the outcomes of the foreclosure process are significantly related to: loan characteristics including the borrower’s credit history, current loan-to-value and the presence of a junior lien; the borrower’s post-default payment behavior, including the borrower’s participation in foreclosure counseling; neighborhood characteristics such as foreclosure rates, recent house price depreciation and median income; and the borrower’s race and ethnicity.     

Ranking Research Productivity in Accounting for Asia-Pacific Universities

Using a set of 18 accounting journals and a sub-set of top five journals from 1991 to 2002, we rank the research productivity in accounting for a total of 119 Asia-Pacific universities. For the whole sampling period, the top five universities are the University of New South Wales, Hong Kong University of Science and Technology, Nanyang Technological University, the University of Sydney, and City University of Hong Kong. A number of prominent universities with long school history are not ranked in the top 20. During the second half of the sampling period, Hong Kong and Singaporean universities have shown the most improvement while some Australian universities have exhibited decline in research output. Also, Hong Kong University of Science and Technology replaces University of New South Wales as the first-ranked university in the period of 1997–2002. When compared with other North American universities, the accounting productivity of the top 20 Asia-Pacific institutions is comparable with that of leading universities in North America. The comparison is even more favorable to the Asia-Pacific universities during the period of 1997–2002.     

Dory & Nemo Early Learning Center

The case requires students to evaluate the current situation and growth options of a small business, Dory & Nemo Early Learning Center (D&N), which provides intergenerational programming to preschool children at a retirement home. The learning center was opened in September 2014, and it was able to make a small profit each year. However, it is projected that there would be a 75 percent decrease in net income from $8,072 in Fiscal 2016 to $1,819 in Fiscal 2017. Davis and Nathans, business partners of D&N, met to discuss the following growth options: (i) Mosaic Retirement Residences' proposal to set up two learning centers at their retirement homes each year for a total of six in three years and (ii) Harmony Retirement Residences' proposal for leasing space to set up learning centers at their retirement homes, one new learning center a year for a total of three in three years. Furthermore, Davis and Nathans had decided to increase the program fee from $320 to $350 per week for the 2017–18 academic session in September. They would also like to reduce their workload from 50 to 40 hours per week, increase their vacation time from two to three weeks, and increase their salaries and bonuses. Students must consider personal objectives of business partners and mission of D&N in the analysis. They learn to identify relevant information for decision making, apply appropriate analytical tools for quantitative analysis, integrate qualitative and quantitative factors in decision making, and make recommendations consistent with analysis.
