摘要

我们建立了一个微观离散-连续需求模型，该模型将logit参与决策与以购买为条件的Cobb-Douglas使用相结合。该结构提供了个人需求、采用概率和福利的封闭形式表达式，为发生率和条件数量方程相乘的实践提供了规范基础。透明的弹性分解将使用与采用响应分开，产生单调的比较静态，并保留随机效用对数和福利。扩展包括多项逻辑共享的多产品采用。

Adoption–usage demand: A discrete–continuous microfoundation

We develop a microfounded discrete–continuous demand model that couples a logit participation decision with Cobb–Douglas usage conditional on purchase. The structure delivers closed-form expressions for individual demand, adoption probabilities, and welfare, providing a normative foundation for the practice of multiplying incidence and conditional quantity equations. A transparent elasticity decomposition separates usage from adoption responses, yields monotone comparative statics, and preserves random-utility log-sum welfare. Extensions include multi-product adoption with multinomial logit shares.

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
