Technological change and factor mix over the product cycle: A model of dynamic comparative advantage

This paper presents a simple dynamic model of how, for a given set of factor prices, the optimizing mix of factor inputs changes over a product cycle, and of how (as a result) comparative advantage in international trade shifts. The model is designed to be consistent with, and to explain, the following stylized facts. When a new technology comes into being, follow-on improvements of the original basic design tend to occur at a rapid rate. Opportunities for improvement and the nonroutinized nature of the production process put a premium on flexibility and insight. As the technology settles down, the premium placed on problem solving ability declines, obsolescence of equipment occurs less rapidly, and unskilled workers and machinery are substituted for skilled workers.     

A Supply and Demand Exposition of the Operation of a Gold Standard in a Closed Economy

Knowledge Effects on Curiosity and New Product Advertising

Abstract

Advertisers commonly advocate when writing ad copy, “Keep it simple!” In keeping with this belief, ads are typically written at less than the tenth grade level. The authors assert that this view may be too simple in view of the complex processes underlying cognitive processing. In an experiment where print ads did not vary in terms of their concreteness, the authors found that increasing levels of readability made no differences in recall, attitudinal judgments or purchase intent.     

Modeling Accounting Workplace Interactions with Text‐to‐Video Animation

This article describes a new pedagogical tool, text‐to‐video animation software, that accounting instructors can adopt to easily generate quality videos that address a variety of accounting learning objectives. Although this tool can be used to enhance traditional pedagogical methods, such as case analysis and discussion, it can also be used to address accounting learning objectives not currently addressed by traditional pedagogical methods. This article outlines the benefits of adopting and using this tool in financial and managerial accounting courses, and encourages further study of its effectiveness.
