Adoption of new tobacco varieties in Greece: Impacts of empirical findings on policy design

Greece is a major international tobacco producer. Flue-cured tobacco varieties constituted the major alternative crop to Greek farmers growing certain oriental tobacco varieties. Diffusion of flue-cured tobacco was rapid due to its high yields and the depressed market for certain oriental tobacco varieties. Currently, the common organisation of the tobacco market is undergoing substantial changes, and the farmers' response will be a vital factor of success. A portfolio selection model reveals that the major factors influencing the adoption decision of tobacco growers are the size of the farm measured in annual work units, the farm's proximity to urban centres, the farm's diversification and the farmer's age. The number of contacts with institutions is, surprisingly, inversely related to adoption. Future tobacco policies impinging on factors influencing decisions to adopt new varieties or production practices may be more cost-effective.     

Stock markets and terrorist attacks: Comparative evidence from a large and a small capitalization market

An expanding body of literature has investigated the economic impact of terrorist attacks. A part of this literature has focused on financial markets. We examine three research questions: whether markets' reactions to terrorism have changed through time; whether market size and maturity determine reactions, and whether reactions depends upon either the type of targets or the perpetrators of the attack. To this effect, a large – the London stock exchange – and a small – the Athens stock exchange – capitalization markets are used as the vehicles for the empirical investigation. Results from an event study methodology as well as from conditional volatility models suggest that size and maturity as well as specific attributes of terrorist incidents are possible determinants of markets' reactions.     

Greening the lodging industry: Current status,trends and perspectives for green value

The purpose of this paper is to provide a critical review of extant knowledge on green lodging integration and a compilation of empirical studies that examine the greening of the lodging industry, published between 2003 and 2014. Empirical academic studies are grouped in three pillars: (a) studies that focus on corporate perspective, (b) studies that examine the role of governmental and trade organizations and (c) studies that focus on consumers’ perceptions in regard to hotels’ green integration. Accumulated knowledge is further presented in a structured way, through a Summary Table. Finally, the paper aims at setting the future research agenda in the area of green lodging by highlighting areas where results are equivocal, areas with evolving research attention and research issues that would enhance our understanding towards a greener lodging industry.     

Importance and Need for Rural Development Instruments Under the CAP: A Survey of Farmers' Attitudes in Marginal Areas of Greece

The present work assesses the attitudes towards importance and need for providing agricultural development instruments other than traditional grant aid mechanisms in rural areas. Assistance in marketing farm produce, provision of extension services on new agricultural technology, agricultural training and provision of quality standards are four of the instruments examined. The importance and need for providing these instruments depends upon producers' human capital accumulation and farm characteristics. The analysis indicates that different instruments may apply to different parts of the rural population and thus a flexible, multi-instrument and selective rural development policy may be required.     

The Day After Grant-Aid: Business Development Schemes for Small Rural Firms in Lagging Areas of Greece

This paper investigates the need for providing follow up business development instruments to small rural businesses that have benefited from grant aid assistance schemes. A sample of 76 small rural businesses in lagging areas of insular Greece is included in the present survey, and ranks thirteen possible business growth instruments. It is found that business development instruments are ranked according to each firm's economic and human capital characteristics. Furthermore, most firms need the concurrent provision of more than one instrument. Likewise, a mixture of business specific schemes, regulatory interventions and infrastructure projects, better serves their business development needs. Results from the present survey indicate that an integrated business development strategy in lagging areas of Greece should be supported by modern, flexibly tailored combinations of assistance, using complex, multi-instrument sets of support to development efforts.     

Productive efficiency and firm exit in the food sector

This work examines the effects of productive efficiency on the survival of firms in the Greek food sector. Technical and scale efficiency scores are computed within a data envelopment analysis (DEA) framework and are used as explanatory variables in a parametric (Weibull) survival model. High technical efficiency increases the median survival time and lowers the hazard rate of exit. As the scale efficiency of a firm operating either at increasing or decreasing returns to scale approaches one (1), its theoretically maximum value, the expected median survival time, is maximized for all types of exits. Developments in biotechnology, the evolution of alternative food supply networks, innovations in the food sector and competition policy are likely to affect technical and scale efficiency of food manufacturing firms. Results unraveling the effects of technical and scale efficiency on the survival of firms in the food sector are of particular relevance to food policy makers.     

Adoption of agricultural innovations as a two-stage partial observability process

In this paper, we reconsider the appropriateness of certain statistical analyses in innovation adoption studies and suggest that partial observability models may sometimes be more useful. The proposed models allow for a flexible specification of the process of adoption from one stage to two stages, facilitate the modelling of non‐adopters and remedy the violation of the assumption of full information. An application to the adoption of organic cultivation in Greece demonstrates the relative merits of the proposed analysis.     

Cost-effectiveness analysis of secukinumab for the treatment of active psoriatic arthritis: a Canadian perspective

Objective: The study evaluates the cost-effectiveness of secukinumab, a fully human monoclonal antibody that selectively neutralizes interleukin (IL)-17A, vs currently licensed biologic treatments in patients with active psoriatic arthritis (PsA) from a Canadian healthcare system perspective.

Methods: A decision analytic semi-Markov model evaluated the cost-effectiveness of secukinumab 150?mg and 300?mg compared to subcutaneous biologics adalimumab, certolizumab pegol, etanercept, golimumab, and ustekinumab, and intravenous biologics infliximab and infliximab biosimilar in biologic-naive and biologic-experienced patients over a lifetime horizon. The response to treatments was evaluated after 12 weeks by PsA Response Criteria (PsARC) response rates. Non-responders or patients discontinuing initial-line of biologic treatment were allowed to switch to subsequent-line biologics. Model input parameters (Psoriasis Area Severity Index [PASI], Health Assessment Questionnaire [HAQ], withdrawal rates, costs, and resource use) were collected from clinical trials, published literature, and other Canadian sources. Benefits were expressed as quality-adjusted life years (QALYs). An annual discount rate of 5% was applied to costs and benefits. The robustness of the study findings were evaluated via sensitivity analyses.

Results: Biologic-naive patients treated with secukinumab achieved the highest number of QALYs (8.54) at the lowest cost (CAD 925,387) over a lifetime horizon vs all comparators. Secukinumab dominated all treatments, except for infliximab and its biosimilar, which achieved minimally more QALYs (8.58). However, infliximab and its biosimilar incurred more costs than secukinumab (infliximab: CAD 1,015,437; infliximab biosimilar: CAD 941,004), resulting in higher cost-effectiveness estimates relative to secukinumab. In the biologic-experienced population, secukinumab dominated all treatments as it generated more QALYs (8.89) at lower costs (CAD 954,692). Deterministic sensitivity analyses indicated the results were most sensitive to variation in PsARC response rates, change in HAQ, and utility values in both populations.

Conclusions: Secukinumab is either dominant or cost-effective vs all licensed biologics for the treatment of active PsA in biologic-naive and biologic-experienced populations in Canada.     

Back to basics: The Comanor–Wilson MES index revisited

The present article attempts to investigate the validity of the Comanor–Wilson Minimum Efficient Size (MES) measure. The basic assumption is that firms that have exhausted scale economies are in non-increasing returns to scale. The same firms are also assumed to have a size greater than MES estimated on sales (total turnover), employment or fixed assets. Data Envelopment Analysis (DEA) is used, on a sample of firms in three Greek manufacturing industries, to classify firms in operation according to increasing or non-increasing returns to scale. On the basis of the results of the DEA input oriented model, the MES measure correctly predicts over 85% of the cases. A probit model is applied to those cases that are not identically predicted by MES concerning returns to scale. Results indicate that technical efficiency, size and age are the factors that compel MES to yield the same prediction as the DEA approach.
