Intermediate microeconomics : A modern approach
01 Jan 2006-
TL;DR: The Varian approach as mentioned in this paper gives students tools they can use on exams, in the rest of their classes, and in their careers after graduation, and is still the most modern presentation of the subject.
Abstract: This best-selling text is still the most modern presentation of the subject. The Varian approach gives students tools they can use on exams, in the rest of their classes, and in their careers after graduation.

TL;DR: In this article, the authors argue that the Spengler's double-markup story does not capture the strategic situation faced by a monopoly supply chain and propose a Rubinstein game to solve the problem.
Abstract: This paper argues that the Spengler’s (JPE, 1950) double-markup
story does not capture the strategic situation faced by a
monopoly supply chain. We show that 1) the Spengler’s
double-markup model is equivalent to an extensive game in which
the upstream monopoly has all power to set the intermediate
price, and the downstream monopsony has no bargaining power.
This assumption seems unrealistic. 2) We model this situation
using the Rubinstein bargaining. The equilibrium of our model
does not yield a double markup. Hence, the joint output, the
consumers price, and the total profit is as high as those of a
vertically integrated firm. Moreover, the profit is split
roughly equally between the two firms. 3) Our model has
different implications for the competition policy.

TL;DR: The results show that accounting for choice in neuroeconomic studies is important to understanding the complex regulation of intake, body weight and other related phenotypes.
Abstract: Food intake and obesity related phenotypes are greatly affected by economic factors and yet very little is known about the interaction of economic factors, genetics, behavior, and obesity phenotypes. Recent human population research suggests that a decreasing price of high fat food relative to low fat food has contributed to the current obesity epidemic in humans. The two key elements in this argument are choice and costs. We incorporate these key elements in a closed economy mouse model to study the interactions of economics, genetics, and obesity related phenotypes, using normal mice, and mice with a mutation in the hypothalamus-expressed Tub gene, which has a phenotype of adult onset obesity. Results for both genotypes indicate that as the price of the high fat food falls, consumption of that food increases and consumption of the low fat food declines, but not enough to offset the increase in high fat food so total intake and weight increases, with no statistically-significant differences between genotypes. These results are in contrast to previous literature based on an ad lib, no choice food setting. In addition, in our closed economy model, the Tub mutant showed a numerical and statistically significant increase in body fat percentage and glucose intolerance, whereas these increases were only numerical for the normal mice. Both genotypes showed numerical but statistically insignificant increases in leptin and ghrelin levels. These results show that accounting for choice in neuroeconomic studies is important to understanding the complex regulation of intake, body weight and other related phenotypes.

TL;DR: In this paper , the authors compared the use of Paylater on Shopee and Gojek and found that user age, credit interest rates and consumer satisfaction had a significant effect on purchasing decisions at Shopee Paylater.
Abstract: This study aims to determine the effect of Paylater convenience in the form of user age at registration, payment tenor flexibility, interest rates or fees and consumer satisfaction with purchasing decisions using Pay Later. This study compares the use of Paylater on Shopee and Gojek. The consideration of comparing the two Paylater platforms is because these two platforms rank the most used by Paylater users in Indonesia. The author uses primary data by using a sample of Paylater users in Malang City as research material and using PLS in analyzing the data. The results showed that user age, credit interest rates and consumer satisfaction had a significant effect on purchasing decisions at Shopee Paylater. While on Gojek Paylater, the variables that have a significant effect are credit interest rates and purchase satisfaction.
