Entrepreneurship in the tourism industry: Issues in developing countries

The tourism industry in Malaysia is one of the most important sectors in terms of its contribution to the growth of the nation. The extensive demand on the tourism industry has stimulated the emergence of many small and medium hotels, resorts, and chalets in Malaysia. According to the literature, small and medium hotels are an extension of the entrepreneurial characteristics of the owners/managers of the hotels. In Malaysia, small and medium hotel entrepreneurs (SMHEs) have not been given much attention. Looking at this gap, this study aims to provide a significant result on entrepreneurship issues in Malaysia. The main objective of this study is to examine the characteristics of small and medium hotel owners/managers and the issues and problems they confront in relation to their survivability in the industry. The result revealed that the majority of owners/managers of small and medium hotels were male, middle-aged and older, with secondary and upper level of education, and whose prior specialisations or knowledge were not related to tourism. With strong self-confidence and independent personality characteristics, the majority started to establish their businesses after the financial crisis in 1997–1998. The result also defined small scale to mean hotels with less than 50 rooms, which had been constructed with limited personal funding and bank loans. Information technology was found to be an important tool to promote their hotels, but conventional techniques such as word of mouth and signboards were still significant. The owners/managers of small and medium hotels were in agreement over their weaknesses in terms of lack of knowledge and skills in running the business. At the same time, they also felt that the government should play a more proactive role in promoting the tourism industry.     

Transfer of Technology to Canadian Manufacturing Industries Through Patents

This paper examines the determinants of foreign patent activity in the Canadian manufacturing sector at the industry level. Since foreign patenting is one of the channels of technology transfer to a country, this study could also show the transfer of foreign technology into Canadian industries measured by foreign patent activity. The paper suggests that the patent activity of foreign countries is the most important factor for receiving foreign patents in Canada. Moreover, imports and foreign direct investments are important vehicles this context. The distance between countries has a negative impact on receiving foreign patents. The impacts of R&D intensity and human capital on receiving foreign patents are mixed and insignificant, but industries with a higher R&D intensity are better recipients of foreign patents.     

Entrepreneurship through Bricolage: a study of displaced entrepreneurs at times of war and conflict

ABSTRACT

War and conflict brings about adverse changes for those who are displaced. How do entrepreneurial individuals respond to such adversity to either set-up, or continue with their existing entrepreneurial endeavours that would improve their own livelihood or that of others who have been affected? Whilst previous studies have found local knowledge, networks and resources to be crucial in the development of ventures in the war and conflict context, alienation from mainstream society within the host location often means that to succeed, those who are displaced require alternative strategies and approaches. Through examining the entrepreneurial ventures of six internally displaced entrepreneurs in Pakistan, our study identifies that entrepreneurial individuals find different ways to adapt to the new order, with both internal and external bricolage becoming the key strategies deployed to either re-establish their previous businesses or to develop new endeavours in the host location. To compensate for lack of local knowledge, networks and resources, we found that entrepreneurs followed closely their previous paths in their bricolage attempts, relying on reconfigurations of their pre-existing competencies, as well as utilizing pre-established and clandestine networks.

A Ricardian Analysis of the Distribution of Climate Change Impacts on Agriculture across Agro-Ecological Zones in Africa

This paper examines the distribution of climate change impacts across the sixteen Agro-Ecological Zones (AEZs) of Africa. We combine net revenue from livestock and crops and regress total net revenue on a set of climate, soil, and socio-economic variables with and without country fixed effects. Although African crop net revenue is very sensitive to climate change, combined livestock and crop net revenue is more climate resilient. With the hot and dry CCC climate scenario, average damage estimates reach 27% by 2100, but with the mild and wet PCM scenario, African farmers will benefit. The analysis of AEZs implies that the effects of climate change will be quite different across Africa. For example, currently productive areas such as dry/moist savannah are more vulnerable to climate change while currently less productive agricultural zones such as humid forest or sub-humid AEZs become more productive in the future.

Cooperative and Non-Cooperative Exploitation of the Arcto-Norwegian Cod Stock

A two-agent model for the exploitation of the Arcto-Norwegian cod stock is developed to investigate the economic benefits that can be realized from the resource, and the effect of exploitation on stock sustainability under cooperation and non-cooperation. The two agents are identified in this study as a trawl fishery versus a coastal fishery. Unlike in Munro (1979), where conflicts in the management strategies of agents arise from differences in the perceptions of the discount factor, fishing effort costs, and consumer preferences, here conflicts arise mainly from the differences in fishing gear and grounds, and the age group of cod targeted by the two agents. Using a game theoretic framework, we show that given available data, the optimum optimorum is obtained under cooperation with side payments and no predetermined harvest shares, in which case the coastal fishery buys out the trawl fishery. However, sensitivity analysis shows that if the price premium assumed for mature cod is taken away, the trawl fishery takes over as the producer of the optimum optimorum.
