Retailers and Consumers: The Pass‐through of Import Price Changes

In this paper, we estimate pass‐through rates of import price changes to retail prices across retailers and consumers for apparel purchases in Germany for the period of 2000–07. We find that high‐price retailers do not pass through changes in the import price. Pass‐through rates for low‐price retailers are 53 per cent within three months. Consequently, pass‐through rates for low‐income households are 58 per cent, significantly larger than those for high‐income households. We then present one possible explanation for these observations in a theoretical model with endogenous vertical product differentiation due to bundling an ex ante homogeneous import goods with services. Following an import price change, retailers who sell a cheaper unbundled product change prices to a greater extent than retailers who sell a higher‐priced bundle of product and service.     

Stock Market‐Induced Currency Crises—A New Type of Twins

This paper explores the link between currency crises and the stock market in emerging economies. By integrating foreign stock market investors in a currency crisis model, we reveal a new fundamental inconsistency as a potential crisis trigger: since emerging economies' stock markets often have high returns, whereas central bank reserves grow slowly or decline, the amount of reserves foreign investors can deplete when selling their stocks and repatriating the proceeds grows over time and is considerably higher than funds that have been invested in the stock market. Capital withdrawals of foreign stock market investors can trigger currency crises by depleting central bank reserves, particularly in successful countries with booming stock markets and large foreign investment.     

Regulation and shadow economy: empirical evidence for 25 OECD-countries

New empirical findings for the impact of regulations on economic activities in the shadow economy are presented here. A comprehensive regulation index covering major fields (e.g. labour and product market regulation and the quality of institutions) has been used to analyze the relationship between the density of regulations and the size of shadow economies. The empirical results from 25 OECD countries for the time period 1995–2005 show that—apart from tax burden and tax moral—main causes for the development of the size of shadow economies are labour and product market regulations, overall regulations and poor quality of official public institutions and administration. These findings can provide additional information on policy measures to tackle the problem of growing shadow economies.     

Quality Marks, Metrics, and Measurement Procedures for Business Process Models

The availability of high-quality business process models is a central prerequisite for a successful process management. Nevertheless, in practice process models exhibit a large number of quality deficits, among them grammatical, content-related, and stylistic defects. In addition, there exist only very few approaches to determine the quality of business process models. In this paper, we present the 3QM-Framework, an analytical approach to systematically determine the quality of business process models. The 3QM-Framework makes three contributions: it provides quality marks, metrics, and measurement procedures to quantify the quality level as elements of a theoretically justified quality model. The applicability of the 3QM-Framework has been empirically evaluated in case studies. The results of a survey that was conducted among experts moreover attest its practical relevance.     

Marktorientiertes Sportmanagement: Empirische Analyse des Einflusses der Marketinginstrumente auf die Markenstärke eines Sportevents

During the last two decades, sponsorship as a management and marketing tool has grown remarkably. This enormous economic potential, e.g. in form of sponsoring packages, makes it necessary for the organizers of sporting events to implement a systematic marketing strategy. The present study therefore attempts to measure the effectiveness of the marketing of sporting events using brand equity as an indicator. The theoretical modeling of the brand equity and the empirical examination are case-specifically conducted for the FIFA World Cup 2006 in Germany. The elements of the marketing mix are used as drivers of the brand equity. The empirical examination identifies the product of the World Cup 2006 as the most effective driver of brand equity. Based on these results implications for the management are developed.     

Cost-effectiveness of golimumab for the treatment of patients with moderate-to-severe ulcerative colitis in Quebec using a patient level state transition microsimulation

Objective: To conduct cost-effectiveness analyses comparing the addition of golimumab to the standard of care (SoC) for treatment of patients with moderate-to-severe ulcerative colitis (UC) who are refractory to conventional therapies in Quebec (Canada).

Methods: An individual patient state transition microsimulation model was developed to project health outcomes and costs over 10 years, using a payer perspective. The incremental benefit estimates for golimumab were driven by induction response and risk of a flare. Flare risks post-induction were derived for golimumab from the PURSUIT maintenance trial and extension study, while those for SoC were derived from the placebo arms of the Active Ulcerative Colitis Trials (ACT) 1 and 2. Other inputs were derived from multiple sources, including retrospective claims analyses and literature. Costs are reported in 2014 Canadian dollars. A 5% annual discount rate was applied to costs and quality-adjusted life-years (QALYs).

Results: Compared with SoC, golimumab was projected to increase the time spent in mild disease or remission states, decrease flare rates, and increase QALYs. These gains were achieved with higher direct medical costs. The incremental cost-effectiveness ratio for golimumab vs SoC was $63,487 per QALY.

Limitations: The long-term flare projections for SoC were based on the data available from the ACT 1 and 2 placebo arms, as data were not available from the PURSUIT maintenance or extension trial. Additionally, the study was limited to only SoC and golimumab, due to the availability of individual patient data to analyze.

Conclusion: This economic analysis concluded that treatment with golimumab is likely more cost-effective vs SoC when considering cost-effectiveness acceptability thresholds from $50,000–$100,000 per QALY.
