本文开发了一种衡量因外生冲击或政策变化而导致的家庭或经济体福利变化的指标。该措施可适用于广泛的经济体，包括那些没有扭曲的经济体，以及那些因规模经济、不完全竞争市场、失业和国内扭曲性税收而造成扭曲的经济体。福利变化指标被分解为五个术语，确定了福利影响的五个来源：税收、国际转移和借贷、贸易条件、消费替代和生产替代。该措施易于解释且易于在实践中应用。计算这些项所需的所有统计数据和信息通常都是可用的或可以轻松估计。
This paper develops a measure of the change in welfare of a household or an economy due to exogenous shocks or policy changes. The measure can be applied in a wide range of economies, including those without distortions, and those with distortions due to economies of scale, imperfectly competitive markets, unemployment, and domestic distor- tionary taxes. The welfare change measure is decomposed into five terms, which identify the five sources of welfare impacts: tax revenue, international transfer and borrowing, terms of trade, consumption substitution, and production substitution. The measure is simple to inter- pret and easy to apply in practice. All statistical data and information required to compute these terms are generally available or can be estimated easily.
