The effect of foreign ownership restrictions on stock price dynamics

The Effect of Foreign Ownership Restrictions on Stock Price Dynamics. —This paper uses Finnish data to explore the impact of foreign ownership restrictions on the dynamic properties of domestic stock prices. These restrictions create unrestricted stocks (foreign and domestic ownership) and restricted stocks (domestic ownership). Unrestricted share prices are significantly more volatile than those of restricted shares but their means are not significantly different from each other. The returns on the two types of shares are found to be generated by an error correction model. These results support the hypothesis that the unrestricted share prices tend to overshoot relative to equilibrium with the arrival of new information.     

FAIR VALUE PRICING OF AGRICULTURAL FUTURES IN SOUTH AFRICA

In the South African agricultural (specifically grain) markets an interesting phenomenon exists: where futures and options on grain products exist (i.e. white maize, yellow maize, soy beans, wheat, and sunflower seeds) price discovery in the spot (also known as “cash”) markets is poor, whereas price discovery in the futures markets is considered respectable. Consequently, whenever a spot deal is undertaken, this price is “derived” from the relevant futures market. This severely anomalous phenomenon will be evident: futures are generally labeled “derivatives” because their prices are “derived” from their spot markets, whereas here we have a situation where spot prices are derived from their futures price (specifically the price of the near – as opposed to far – future). Because of this unusual phenomenon the mathematics involved is not readily available in the literature; this article is an attempt to briefly outline the phenomenon and to present the relevant mathematics.     

Does North-South horizontal intra-industry trade really exist? An analysis of the toy industry

Does North-South Horizontal Intra-Industry Trade Really Exist? An Analysis of the Toy Industry. — In a combination of a case study approach and econometric analysis, bilateral intra-industry trade between high income countries and low income countries in the toy industry is investigated. In a number of products there is important bilateral intra-industry trade between both groups of countries. Econometric analysis in which a number of the explanatory variables used were quantified on the basis of the information supplied by the industry-spokesmen yields results which strongly support the view that the bilateral IIT between the high income countries and the low income countries in the toy industry is determined significantly by horizontal product differentiation and economies of scale.     

Two-way trade between unequal partners: The EU and the developing countries

Two-Way Trade between Unequal Partners: The EU and the Developing Countries. — This paper analyses the intra-industry trade specialization between the EU and the developing countries between 1980 and 1992. It shows that EU intra-industry trade with the developing countries has greatly increased and that the traditional measure of intra-industry trade, the Grubel-Lloyd index, is inappropriate when applied to trade between developed and developing countries. By and large, the empirical analysis confirms that intra-industry trade between the developed and the developing countries increases with average and per capita income, and with reduced differences in economic size and capital-labour ratios.     

Exchange rates and European countries’ export prices: An empirical test for asymmetries in pricing to market behavior

Exchange Rates and European Countries’ Export Prices: An Empirical Test for Asymmetries in Pricing to Market Behavior. — This paper uses forward instead of spot exchange rates to test for the presence of asymmetries in the response of export prices to exchange rate movements on a wide sample of European Union exporter countries and highly disaggregated product categories. In most cases, the data give support to the hypothesis of a symmetric pricing to market behavior during periods of depreciation and appreciation of the exporter’s currency.     

Vertical specialization and intra-industry trade: The role of factor endowments

Vertical Specialization and Intra-Industry Trade: The Role of Factor Endowments. — In this paper, we use vertical differentiation models of the Falvey-Kierzkowski type to study the effects of differences in factor endowments on vertical intraindustry specialization. We focus on Spanish intra-industry trade, as Spain typically exports low-quality varieties to the northern countries of the OECD and high-quality varieties to the southern ones. In order to achieve more general results, we consider different types of productive factors: physical, human and technological capital. Our results confirm that factor endowments play a significant role in explaining vertical intra-industry specialization.     

THE CHANGING EFFICIENCY OF AFRICAN STOCK MARKETS

This paper classifies formal African stock markets into four categories and discuses the principal characteristics of the seven markets covered in this study: South Africa, Egypt, Morocco, Nigeria, Zimbabwe, Mauritius and Kenya. Using a GARCH approach with time‐varying parameters, a test of evolving efficiency (TEE) is implemented for periods starting in the early 1990s and ending in June 2001. This test detects changes in weak form efficiency through time. The TEE finds that the Johannesburg stock market is weak form efficient throughout the period, and three stock markets become weak form efficient towards the end of the period: Egypt and Morocco from 1999 and Nigeria from early 2001. These contrast with the Kenya and Zimbabwe stock markets which show no tendency towards weak form efficiency and the Mauritius market which displays a slow tendency to eliminate inefficiency. The paper relates weak form efficiency to stock market turnover, capitalisation and institutional characteristics of markets.     

FURTHER EVIDENCE OF LONG MEMORY IN THE SOUTH AFRICAN STOCK MARKET

This paper expands and augments the results of the paper by Jefferis and Thupayagale ) and tests the efficiency of the South African stock market with Wavelet and Markov Switching Regime analyses of selected shares and the a ALSI 40 data. The Wavelet analysis indicated that most of the individual share prices and the share index time series are mean reverting over the long run and follow a long memory process, offering evidence against weak-form efficient market hypothesis (EMH). The Markov model modelled the financial and prevalent economic conditions accurately and established the presence of patterns in the historic time series, providing additional support against the weak-form EMH.     

A new look at the impact of U.S. import barriers on corporate profit expectations

A New Look at the Impact of U.S. Import Barriers on Corporate Profit Expectations. — The notion that industries benefit from protection is firmly grounded in trade theory. However, previous “event studies” measuring the impact of trade restrictions on stock prices reveal that shareholders expect no improvement in industry profits from protection. The implication is that barriers designed to promote industry adjustment are considered ineffective by equity holders. This investigation of U.S. “Escape Clause” cases shows that shareholders do expect protection to enhance profits, but not universally. Outcomes are linked to the type of trade measure selected, with industries protected by tariffs or global quotas faring better than those shielded by nonglobal “Orderly Marketing Agreements.”     

Size and liquidity effects in Japanese regional stock markets

This paper assesses the effectiveness of traded turnover, Amihud (2002) and Liu (2006) metrics in measuring illiquidity, as used in a multifactor CAPM. The performance of this model is contrasted using a unique sample from Japan’s regional stock exchanges, namely Sapporo, Nagoya, Fukuoka, Osaka and Tokyo. The evidence suggests that size effects are important in Tokyo, liquidity plays a more important role in the conditional modelling of returns particularly in the smaller markets of Sapporo, Fukuoka and Nagoya where costs of equity are highest.
