The differential futures of ski tourism in Ontario (Canada) under climate change: the limits of snowmaking adaptation

The international ski tourism industry is highly vulnerable to inter-annual climate variability and climate change. Accordingly, there is a strong need to advance our understanding of climate risk for this multi-billion tourism market that is so important to mountain regions around the world. This study addressed major limitations in the ski tourism literature, while concurrently supporting priority information needs of ski tourism stakeholders. An improved version of SkiSim 2.0 is applied to all 34 alpine ski areas in southern Ontario (Canada) to examine potential changes in the capacity of this regional marketplace. Model improvements include differential snowmaking capacities of individual ski areas, updated snowmaking decision rules, as well as a new indicator, termed ‘terrain-days’, to estimate changes in system capacity. The results project two fundamentally different futures for this ski tourism marketplace under climate change. If the international community succeeds in achieving the?+?2°C Paris Agreement policy goal, then losses in system capacity can be limited to less than 10% in the mid- and late-century. In contrast, a high-end emission scenario (RCP 8.5) would severely disrupt this ski tourism market by mid-century, with system capacity losses between 28% and 73%.     

Multi-factor financial planning: an outline and illustration

This paper deals with the support of strategically oriented financial planning processes in business firms. In handling a financial planning problem, the decision maker has to deal with a number of complications. In this paper special attention is paid to the risk with regard to the outcomes of the financial plan and the existence of multiple, conflicting goals. An interactive approach to financial planning is presented. Risk is modeled by means of so-called multi-factor risk models and multiple goals are explicitly accounted for through the use of an interactive goal programming method. The use of the interactive approach will be numerically demonstrated by means of an exemplary planning problem.     

Goal programming solutions to transportation problems with variable supply and demand requirements

This article deals with goal programming as an aid to resolving transportation problems. The objective of this study is to demonstrate the use of goal programming as an approach to reducing total cost in transportation problems that possess variable supply and demand requirements. A generalized goal programming model is formulated and applied to a series of transportation problem situations based on the empirical data provided by a medium-size trucking firm. Comparison of the results demonstrates the cost advantage of using the goal programming model in place of the transportation method and integer interval linear programming.     

THE EFFECTS OF LENIENCY PROGRAMS AND FINES ON CARTEL STABILITY

Using a stylized oligopoly model, we analyze the effect of cartel deterring fines, taking into consideration exemptions granted to cartel members cooperating with the competition authorities. We conclude that the fines can act as a deterrent to breaking collusive agreements, thus stabilizing the cartel.     

Creative Destruction, Investment Volatility, and the Average Age of Capital

In this article, a new numerical procedure is used to compute the equilibrium of a vintage capital growth model with nonlinear utility, where the scrapping time is nonconstant. We show that equilibrium investment and output converge nonmonotonically to the balanced growth path due to replacement echoes. We find that the average age of capital is inversely related to output, which is consistent with recent micro evidence reinforcing the importance of the embodied question. We also find that an unanticipated permanent increase in the rate of embodied technological progress causes labor productivity to slowdown in the short run.     

Regional Determinants of Small Firm Loans Under the U.K. Loan Guarantee Scheme

The Loan Guarantee Scheme was initiated in 1981 in order to alleviate a perceived constraint in the ability of small firms to secure bank finance due to a lack of collateral. This paper shows that a national small firms support scheme has, at the point of delivery, had quite different coverage across regions. Briefly, the initial evidence suggests that the Northern regions of England have been the major net beneficiaries of the scheme, primarily at the expense of Northern Ireland and Scotland. Further analysis identified house prices as the single most important determinant of loan size, acting via a collateral effect. On loan numbers and value, fixed regional effects were dominant particularly in the South East and North West.     

SHORT‐MATURITY OPTIONS AND JUMP MEMORY

We investigate jump memory using an extensive database of short‐term S&P 500 index options. Jump memory refers to the attenuation of the implied jump intensity and magnitude parameters following a crash event. We use a genetic algorithm to obtain a time series of implied parameter estimates and posit behavioral and rational explanations for parameter attenuation following a crash event. We find that a nested form of the jump‐diffusion model sharpens the remaining parameter estimates and has a negligible effect on pricing accuracy.
