Generalized Cost-Benefit-Analysis and Social Discounting with Intertemporally Dependent Preferences
نویسندگان
چکیده
We derive a general framework for cost-benefit analysis and social discounting in a setting with intertemporally dependent preferences. Here, the marginal contribution of an additional unit of consumption in some period depends on what is consumed in the other periods. We use a simple model of history dependent preferences to analyze how habit formation affects the social rate of discount. Getting used to good life before a potential decline in growth as well as getting used to bad life during a decline in growth both affect social discount rates, not only during the time of the growth rate change but also before and after.

A new study of an EOQ model for deteriorating items with shortages under inflation and time discounting
We discuss the effects of inflation and time discounting on an EOQ model for deteriorating items under stock-dependent demand and time-dependent partial backlogging. The inventory model is studied under the replenishment policy starting with no shortages. We then use MATLAB to find the optimal replenishment policies. The objective of this model is to maximize the total profit (TP) which inclu...
متن کاملEconomic Order Quantity for Deteriorating Items with Non Decreasing Demand and Shortages Under Inflation and Time Discounting
Some products like green vegetables, volatile liquids and others deteriorate continuously due to evaporation, spoilage etc. In this study, an inventory model is developed for deteriorating items with linearly time dependent demand rate under inflation and time discounting over a finite planning horizon. Shortages are allowed and linearly time dependent. Mathematical model is presented for the p...
متن کاملValuing the Future - Recent advances in social discounting
Prescriptive economics requires that, unless there are very good reasons to the contrary, economic policy should be based on the principle that individuals’ preferences should count. Indeed, the entire body of ‘welfare economics’ centres round the formal identity of the statement “X prefers A to B” and the statement “X has higher welfare in A rather than B”. This combination of a seemingly inno...
متن کاملSpatial Discounting of Food and Social Rewards in Guppies (Poecilia Reticulata)
In temporal discounting, animals trade off the time to obtain a reward against the quality of a reward, choosing between a smaller reward available sooner versus a larger reward available later. Similar discounting can apply over space, when animals choose between smaller and closer versus larger and more distant rewards. Most studies of temporal and spatial discounting in non-human animals use...
متن کاملDiscounting climate change damages: Working note for the Stern review
This working note provides a basic overview of discounting in the context of climate change policy. After defining the social discount factor and social discount rate in terms of shadow prices (section 2), and noting the limitations of cost-benefit analysis for climate change (section 3), the determination of efficient social discount rates is discussed given: the impact of uncertainty about fu...
