Climate change, irrigation, and Israeli agriculture: Will warming be harmful?

This paper utilizes a Ricardian model to test the relationship between annual net revenues and climate across Israeli farms. The study finds that it is important to include the amount of irrigation water available to each farm in order to measure the response of farms to climate. With irrigation water omitted, the model predicts climate change is strictly beneficial. However, with water included, the model predicts that only modest climate changes are beneficial while drastic climate change in the long run will be harmful. Using the AOGCM Scenarios we show that farm net revenue is expected to increase. Although Israel has a relatively warm climate a mild increase in temperature is beneficial due to the ability to supply international markets with farm product early in the season.     

Determinants of vacation travel among Israeli seniors: theory and evidence

This study investigates determinants of vacation travel among seniors. A consumer choice model is developed that incorporates effects of retirement and health on available leisure time, and effects of age and education on disposable income. The empirical implications of the model depend on leisure and income patterns, that in turn determine if time and budget constraints are binding. The model is illustrated using data collected from Israeli seniors. Results confirm theoretical predictions regarding the changing effectiveness of constraints as seniors grow older.     

Non‐linear geographics and the economics of transition and democratization1

The purpose of this study is to analyse the effects of geography on the transition process in authoritarian political regimes, and to investigate the nature of the links between political change, economic reforms and geographical location. A simple model of transition and democratization is presented wherein we show that the effectiveness of repression by the incumbent elite is a negative function of the distance to the ‘free world’. In consequence, geography has conflicting effects on shifts in political power. This article provides a rationale for the counterintuitive fact that the first authoritarian country to start a transition process towards democratization is not necessarily the one nearest to the free world.     

A room with a view—A valuation of the Mediterranean Sea view

Aesthetic view is one of the ecosystem services of the Mediterranean Sea which can be estimated using price differences in the hotel market. Hotels situated on the Mediterranean Sea charge higher prices for a room with a sea view than for a room without it. The value of this view in 10 major Mediterranean regions was estimated in this paper using a hedonic price method. Data on 2819 hotel rooms in high season and 2406 rooms in the low season were collected from Booking.com and fixed effects regression was used to estimate the model coefficients. Hotel room prices were found to be higher by about 10% for a room with a view than for one with no view specification. No significant difference was found between regions or season. These findings lend support to the fact that the view of the Mediterranean is equally valued in all regions.     

Measuring the Recreational Value of Open Space

We develop aggregate measures of the recreational value of types of open space when data on individual site visitation are not available. Our procedure accounts for both the allocation (between the different types of open space) and participation (total number of trips) decisions. The procedure is applied to estimate the recreational value of three types of open spaces (beaches, urban parks and national parks) in Israel.     

Early Birds versus Just-in-Timers: The effect of procrastination on academic performance of accounting students

This study investigates the effect of procrastination on academic performance. Prior research has often relied upon self-reported measures of procrastination, which are only weakly correlated with actual procrastination. We use the start and submission of a set of online homework problems as two objective, direct measures of student procrastination and the grade on the assignments as a measure of performance. In our study, there were a number of potential benefits to submitting online assignments ‘just-in-time’. Thus, there was a direct benefit to procrastination, which students had to weigh against potential drawbacks. With a sample size larger than those previously reported in the literature, we find that for both procrastination measures, task procrastination is associated with lower task performance. To ensure that our results are not just an association between performance and student quality, we test for the association between task procrastination and task performance, while controlling for student quality. We find that even after controlling for student quality, task procrastination is associated with lower task performance.     

Rural poverty in Mexico: assets and livelihood strategies among the Mayas of Yucatán

Understanding poverty and sustainability needs livelihood studies that acknowledge heterogeneity at the community and household level. This is particularly true for Latin America where inequality and ethnicity are important aspects of poverty and sustainability. This paper is a detailed examination of the natural resources, socio-economic assets and livelihood strategies of two Mayan communities of the Mexican State of Yucatán. There were three fundamental objectives: to elucidate the people's perceptions of poverty, to analyse their resource use and livelihood strategies, and to suggest ways in which access to markets can reduce poverty and enhance sustainable development. Using qualitative and quantitative methodologies, the dominance of certain successful strategies are made clear. First, milpa—the traditional system of maize production—is a way of life for the Mayas. Secure access to maize-producing land is a valuable asset, partly because it also attracts government subsidies. Second, ownership of small livestock is also part of Mayan life. Ownership of other assets such as beehives gives access to (relatively) lucrative product markets. Third, active agribusiness marketing also requires assets: ownership of transport services; finance to assemble and sell products such as forest fruits, honey and maize; business skills and an ability to create commercial linkages to traders. Appropriate interventions for different wealth groups are suggested to enhance sustainable development of the communities.     

The new views on demographic transition: a reassessment of Malthus's and Marx's approach to population

The purpose of this paper is to examine the divergence of views of Marx and Malthus regarding the family and the labour market. The paper analyses the divergences between them, as well as their common features. The main divergence is the way in which the two see the interaction between man and nature. We show that their divergence of views, and the specific difference in perception of the two thinkers regarding the place of children in the family over time, is related to the alternate ways of modelling demographic transition today. We analyse the debate between these two lines of reasoning by means of a formal model that differentiate between the two views.     

What do Airbnb hosts reveal by posting photographs online and how does it affect their perceived trustworthiness?

The use of sellers' personal photographs online is ubiquitous in sharing economy platforms such as Airbnb. This paper addresses two questions. First, what type of personal photos do hosts choose to post on Airbnb? Second, which of the characteristics of their photos affects their perceived trustworthiness? We answer these questions by building a structural equation model of the relation between the characteristics of the photos and the perceived trustworthiness of the hosts. The antecedents of trust in this model were defined based on insights from psychology regarding first impressions. We found that the hosts' visual characteristics (e.g., gender) as revealed in their online photographs affect their perceived trustworthiness both directly and indirectly via attractiveness. We also found that image characteristics, which are not related directly to the traits of the host in the picture (e.g., photograph quality), play a significant role in trust inference. Interestingly, the hosts' choices of their personal photos suggest that they may not be aware of these effects.     

Price level determinacy and the choice of policy targets under rational expectations

We show that in a conventional macro model with rational expectations, the government can use monetary policy to peg real interest rates, and still attain a determinate price level provided it also pegs some nominal policy variable, e.g., nominal expenditures.
