Is South Korea’s stock market efficient?

This letter applies the Zivot and Andrews (Journal of Business and Economic Statistics, 10, 251-70, 1992) one break and the Lumsdaine and Papell (Review of Economic and Statistics, 79, 212-8, 1997) two break unit root tests to examine the random walk hypothesis for stock prices in South Korea. The results provide strong evidence that stock prices in South Korea are characterized by a unit root, which is consistent with the efficient market hypothesis.

Cointegration of stock markets between New Zealand, Australia and the G7 Economies :searching for common trends under structural change

This paper examines whether the New Zealand equity market is integrated with the equity markets of Australia and the G7 economies by applying both the Johansen (1988) and Gregory and Hansen (1996) approaches to cointegration. The Johansen (1988) test suggests that there is no long-run relationship between the New Zealand stock market and any of the other stock markets considered in the study. The Gregory and Hansen (1996) test finds that the New Zealand and United States stock market is cointegrated, but the New Zealand stock market is not cointegrated with the other stock markets in the study. This suggests that in order to avoid some of the risk through international portfolio diversification there is potential for investors to purchase shares in the New Zealand market and either the Australian market or most of the world’s leading equity markets.

Are OECD stock prices characterized by a random walk? Evidence from sequential trend break and panel data models

This paper examines whether stock prices for a sample of 22 OECD countries can be best represented as mean reversion or random walk processes. A sequential trend break test proposed by Zivot and Andrews is implemented, which has the advantage that it can take account of a structural break in the series, as well as panel data unit root tests proposed by Im et al., which exploits the extra power in the panel properties of the data. Results provide strong support for the random walk hypothesis.

Interdependence and dynamic linkages between the emerging stock markets of South Asia

The present article examines the dynamic linkages between the stock markets
of Bangladesh, India, Pakistan and Sri Lanka using a temporal Granger causality
approach by binding the relationship among the stock price indices within a
multivariate cointegration framework. We also examine the impulse response
functions. Our main finding is that in the long run, stock prices in Bangladesh,
India and Sri Lanka Granger-cause stock prices in Pakistan. In the short run
there is unidirectional Granger causality running from stock prices in Pakistan
to India, stock prices in Sri Lanka to India and from stock prices in Pakistan to
Sri Lanka. Bangladesh is the most exogenous of the four markets, reflecting its
small size and modest market capitalization.

Retrofitting for ventilation, infiltration and comfort

Legislation is demanding that our existing building stock be improved to a minimum of 4.0 Star AGBRS (Aust. Green Building Rating Scheme) energy standards. In the 'Green Building Fund' scheme for office buildings and other government incentives, retrofitting our existing building stock makes plain good sense. However, many of the stakeholders (owners, facilities managers, occupants) do not know where to begin to invest, for making these savings. This paperdemonstrates through two case studies, in government related  office buildihgs,how real energy savings were approached and obtained. It illustrates a process whereby preliminary and pretesting results lead to solutions of building ventilation, infiltration and comfort improvement. Furthermore, it discusses how post building performance testing results verified improvement as well as provided inputs to energy simulation, indicating where further invested improvements could be made.
One case study illustrates how the weatherisation of a building prevented a 1.5 million dollar retrofitting spending, costing the client less than one-tenth of the initial retrofitting cost. Another example demonstrates how over-engineering and incorrect ventilation concepts can cost the client up to 70% of their energy bill. Both papers involve real evidence-based pre and post measurement results in existing occupied buildings.

Portfolio diversification and share price behavior : some evidence from the Taiwan Stock Exchange

This dissertation consists of four separate but closely related studies which investigate different aspects of share price behavior on the Taiwan Stock Exchange over the period 1980-89: 1.The benefits of diversification available to investors using the Markowitz model and the Single Model Index. 2. The applicability of the CAPM to the TSE over the decade. 3. Regularities in proce sequences. 4. Market reaction to the announcements of stock dividends, right issues and combinations of both.

Stock-in-trade valuation in the United Kingdom 1840 to 1959

Commentators have made a number of unsubstantiated claims about why the lower of cost and market rule had become the accepted method of valuation. It is demonstrated that none of these explanations can be substantiated. Leon Festinger's theory of "dissonance reduction" is used to explain why the significant criticisms of the rule have been ignored.

The potential use of otoliths for pilchard stock discrimination

Pilchards were collected from south-eastern Australian waters and aged by counting growth rings on their ear bones (otoliths). Differences in growth and population age structures were compared between regions. The shape characteristics of the ear bones were also examined using rapid, objective, semi-automated methods. Differences between the areas were shown.

Efficiency and unbiasedness in the Indian stock index futures market

This paper explores potential efficiency and unbiasedness as well as the degree of efficiency in stock index futures of an emerging market using both monthly and daily data. Besides analyzing efficiency and unbiasedness with cointegration and error correction model, the degree of efficiency is further investigated after explicitly modeling the underlying state of the market (expansion or contraction) through the first-order Markov switching set-up. The results show that a relatively longer two-month horizon is more effective in eliminating arbitrage opportunities than the short run (one-month and daily) futures.

Market liquidity risk factor and financial market anomalies : evidence from the Chinese stock market

The Chinese stock market is an order-driven market and hence its characteristics are structurally different from quote-driven markets. There are no studies that consider the role of the market liquidity risk factor in determining cross-sectional stock returns in a model including financial market anomalies for order-driven markets. Our aim is to test whether financial market anomalies such as firm size, the book-to-market ratio, the turnover rate, and momentum both with and without the inclusion of the market liquidity risk factor in the case of the Chinese stock market can explain cross-sectional stock returns. The empirical framework is based on the model proposed by Avramov and Chordia (AC, 2006). Our main finding is that the AC model can capture financial market anomalies except momentum when we include the market liquidity risk factor on the Chinese stock market.
