Estimating switching costs after introducing Fixed-Mobile Convergence in Japan

In this study, based on a conjoint-type survey analysis, the switching cost of several Japanese telecom services are empirically examined simultaneously, contingent on each carrier’s bundling strategies. The results suggest the following conclusions. The hierarchy of switching costs is mobile phone service, fixed phone service, ISP (Internet Service Provider), and broadband access service, in descending order. Even if the government prohibits the formerly state-owned monopoly NTT from forming alliances with other carriers, the legacy NTT group would still command more than half of the market share under FMC if each carrier adopts a pure bundling strategy. If mixed bundling emerges as the primary strategy in the FMC market, the resulting type of competition from the introduction of FMC does not stimulate competitive pricing.     

Parity reversion persistence in real exchange rates: middle income country case

This article investigates purchasing power parity (PPP) in the specific context of middle income countries. To circumvent the low power of traditional stationarity tests (Augmented Dickey-Fuller and Phillips-Perron tests), it performs variance ratio and fractional integration tests in addition to Perron's test that accounts for potential structural changes in real exchange rate processes. Beyond estimating half-life shocks to PPP, this article attempts to explain these estimates using a set of country specific variables as suggested by economic theory. The evidence suggests that reversion to parity tends to be faster in high inflation countries and that productivity improvement leads to a higher level of persistence. Openness to trade tends to reduce the extent of deviations from parity but this result does not appear to be statistically robust. Evidence shows also that deviations are less persistent under a fixed exchange rate regime and under unrestricted capital mobility.     

Liquidity and market makers: a pseudo-experimental analysis with ultrahigh frequency data

An analysis is given of the effect of market makers on liquidity using a transaction-level database. For this purpose, the focus is on a financial market where a change in regulations created explicitly the category of market maker in 1997 and that date is used to construct a pseudo-experiment. In contrast with other studies that use ultrahigh frequency data, the days to be analysed are selected using a statistical procedure to match observations before and after the change in regulation. The propensity score is used to perform the matching. After choosing the days, an estimate of an ordered probit model is made to explain the intraday behaviour of price changes. The coefficient estimates from the ordered probit model are used to calculate a measure of liquidity based on the steepness of the response function of price changes to volume. The results show that liquidity, measured in this way, has not been affected by the introduction of the market makers.

THE HEALTHCARE VOUCHER: EMERGENCE,FORMATION AND DISSEMINATION

Market‐inspired healthcare reforms have been introduced in Sweden: Freedom of Choice in Healthcare in 1989 and the National Healthcare Guarantee in 2005. After the general election 2006 the idea of the Healthcare Voucher has followed. Built on a theoretical framework composed of Foucault's concept of 'discursive formation' supported by Butler's concept of the ‘performativity of discourse’ the purpose is to analyse the emergence, formation and dissemination of this idea into healthcare in Sweden. The Voucher is disseminated in a form reminiscent of a chain linking a series of texts, referring to each other and building on each other's formulations strengthening each other's messages. It circulates under designations such as healthcare voucher and money and seems to be disseminated by being combined with 'freedom of choice' forming the theme customer choice. The Healthcare Voucher then becomes a means of being able to realise an idea of a political nature, building markets in healthcare. The paper offers a way of analysing how ideas influence the policy agenda, in particular for the voucher/s. Distinctions could be made between the voucher idea and 'money following the patient' in quasi markets. A critical issue in introducing choice and competition, not explored here, is the issue of ‘cream skimming’.     

A critique of Porter＇s cost leadership and differentiation strategies

Porter identifies high market share with cost leadership, citing GM as a successful practitioner of this strategy. However, GM became a market share leader in the American automobile industry due to a strategy of market segmentation, differentiation and a broad scope shaped during the 1920s. Porter argues that cost leadership and differentiation offer an equally viable path to competitive success. Nevertheless, a differentiation strategy based on superior quality compared to competition is more profitable than cost leadership strategy. It can lead a business to become a market share leader, and consequently even a low-cost leader. Research indicates that differentiation and cost leadership can co-exist. However, Porter insists that each generic strategy requires a different culture and a totally different philosophy. The problem is that Porter＇s generic strategies are too broad. It is not his logic that is flawed, but his basic premise that prescribes cost leadership strategy as the only route to market share leadership, and presents a narrow view of differentiation with a unique product--sold at a premium price--on the one hand, and a ＂standard, or no-frills＂ product on the other. Mintzburg （1988） says Porter＇s cost leadership strategy should be called ＂price differentiation＂： a strategy that is based on a lower price than that of the competition. He suggests that business strategy has two dimensions： differentiation and scope. Thus, setting scope aside, competitive strategy has only one component： differentiation. So, the key question is not whether to differentiate, but how？ First, make customer-perceived quality as the foundation of competitive strategy because it is far more critical to long-term success than any other factor. Second, serve the middle class by competing in the mid-price segment, offering better quality than the competition at a somewhat higher price. It is this path that can lead to market share leadership--a strategy that can be both profitable--and sustainable.
