How do consumers categorize new hybrid products?

This article investigates how consumers categorize new hybrid products (NHPs). Given the limitations of the classical theories of categorization in the specific case of NHP, affordance, mobilized infrequently in marketing, turned out to be a useful categorization concept. Five types of NHP categorizations by consumers, based on the degree of affordance (low vs. high) and type of innovation (incremental vs. radical), have been detected and filled a gap in the literature on the subject.     

Utility decrements associated with side effects in schizophrenia

Objective:

Most of the existing studies investigating the impact of schizophrenia on utility have focused on the different stages of the disease. The objective of this study was to describe and quantify the impact of treatment-related side-effects on utility in patients with schizophrenia, using data from an observational study.

Methods:

This study used data from the European Schizophrenia Cohort (EuroSC), a multi-center 2-year cohort study conducted in France, England, and Germany. The EQ-5D questionnaire was completed every 6 months, as well as the Subjective Side Effect Rating Scale, assessing patient distress over extrapyramidal symptoms (EPS), weight gain, sedation, and sexual dysfunction, used to assess whether or not the patient experienced the side-effect. At first a bivariate analysis was conducted to describe utility values with and without side-effects. Then, a random effects regression analysis was performed on utility, where random effects were controlled for repeated measures on the same subjects, with potential confounding factors. Finally, findings were compared with those of previous publications.

Results:

This sample consisted of 1208 patients with schizophrenia. At the baseline visit, the most reported side-effect was EPS (almost 60% of patients), followed by sedation and weight gain (～50% of patients for each), and sexual dysfunction (almost 30% of patients). Significant association with severity of symptoms, functioning abilities, and utility were found. Patients reporting none of the studied side-effects had an average EQ-5D index score of 0.81, found to be higher than scores of patients reporting EPS (0.70), sexual dysfunction (0.67), sedation (0.70), or weight gain (0.72). The random effects model reported a utility decrement of 0.042 for EPS, 0.022 for weight gain, 0.022 for sexual dysfunction, and 0.019 for sedation. Although the external validation was difficult due to the different methods or definitions of the side-effects, as well as the paucity of data for weight gain, sedation and sexual dysfunction, the results were generally consistent with previous studies.

Conclusion:

This study aimed at quantifying the direct impact of main side-effects associated with antipsychotics on patients’ utility. Results suggested a significant direct impact of side-effects, with EPS being the most impactful.     

Some Empirical Indications of the Relationship Between Environmental Quality and Economic Development

The paper examines the relation between countries' state of the environment (defined as acceptable, marginal or unacceptable, according to values of ambient accumulation of pollutants) and stage of economic development (defined as low, middle and high income), using the concentration of sulphur dioxide in urban areas and dissolved oxygen in rivers. Univariate and ordered probit models are estimated for air and water quality. The results indicate that the probability of having acceptable environmental quality in a country increases with respect to the examined pollutants as the country moves to a higher state of economic development.     

Convergence in household credit demand across euro area countries: evidence from panel data

This article contributes to the literature on the convergence of financial systems in the euro area by estimating household credit demand in individual countries. Using the ARDL framework advocated notably by Pesaran et al. (1999 Pesaran, MH, Shin, Y and Smith, RP. 1999. Pooled mean group estimation of dynamic heterogeneous panels. Journal of the American Statistical Association, 94: 621–34. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), the article provides evidence on the convergence of long-run credit demand determinants (interest rates, investment and house prices) in the largest euro area countries, while short run-dynamics remain heterogenous across countries. The article also demonstrates that the equation uncovers demand rather than supply behaviour.     

Capital Surges and Credit Booms: How Tight is the Relationship?

It has been frequently argued that surges in capital inflows are a major cause of credit booms and banking crises in emerging market economies. This view suggests that there is little role that can be played by domestic policy to break this linkage. This need not be the case. We show that the linkage between surges and booms is not as strong as is often assumed. One problem with most previous studies is that a wide range of measures for both surges and booms has been used with little checking of the robustness of results. We deal with this issue by replicating 14 different measures of capital surges (gross and net) and 5 credit boom proxies from the literature on a sample of 46 countries from 1981–2010. A second difficulty is that some previous studies have not distinguished between the proportions of surges followed by booms and booms preceded by surges. We found substantial differences between these two relationships. While there is a good deal of variation in the individual correlations the vast majority of the calculated probabilities of a surge being followed by a credit boom fall within the range of 4 % to 13 %. Although the proportion of credit booms preceded by surges is higher, the correlations for both directions are much lower than are frequently assumed. While the probabilities of a surge being followed by a credit boom generally increased from the 1980s to the 1990s they fell again in the 2000s, suggesting the possibility that authorities have become better at limiting the adverse effects of surges on domestic credit growth.     

Stress testing and corporate finance

The article contributes to the literature on financial fragility, studying how macroeconomic shocks affect supply and demand in the corporate debt market. We take into account the effect of the competitive environment, as well as the risk level, measured by companies’ default rate. The model is estimated using data from the Harmonised BACH database of corporate accounts for large euro area countries on the 1993–2005 period, in order to carry out an illustrative stress testing exercise. We measure the impact of large macroeconomic shocks (a severe recession and a sharp increase in oil prices) on the equilibrium in the debt market.     

Political credit cycles

This paper tests the existence of political credit cycles, the positive comovement between credit and elections. While several single‐country studies point to the existence of this relationship, the link between electoral cycles and credit expansion has seen little exploration at the multicountry level. Using a comprehensive dataset covering bank and non‐bank credit in 165 countries from 1960 to 2013, we show that both government and private credit significantly increase in election years. This finding suggests the possibility that politicians use not only fiscal and monetary policy to court voters, but also implement credit policies such as interest rate subsidies and tax breaks for debt to enhance credit growth. We also find that a higher degree of financial openness weakens the frequency and magnitude of political credit cycles; yet, the conditional effect of financial openness is stronger for developing countries than developed economies.     

Macroeconomic coordination failure under oligempory

Summary. Each sector of a multi-sector overlapping generations model is an oligempory with a given number of firms, oligopsonists in the sectoral (spatially differentiated) labour market and oligopolists in the sectoral (homogeneous) output market. When there is aggregate unemployment, and a firm raises wages beyond the local full employment level acquiring labour from neighbours, sectoral output supply becomes constant and the firm faces a flat output demand curve under constant returns to labour (upward sloping under decreasing returns). Multiple temporary equilibria and Pareto-ranked steady-state equilibria emerge; the associated sunspot equilibria exhibit counter-cyclical markups, inter alia.
