مدل انتظارات عقلایی برای تجزیه و تحلیل سیاست های مالیاتی: ارزیابی مشوق های مالیاتی برای صنایع نساجی، شیمیایی و دارویی پاکستان

An intertemporal model of a firm optimizing its expected net present value was used to derived the modes's estimating equations, and rental prices of capital services consistent with rational expectations. We analysed the effects of a 10 percent change in two tax incentives. For the chemical and pharmaeutical industries the benefits of the tax credit for physical investment (increased investment) far exceeded it costs (forgone tax revenue). This was also true for the R&D tax allowance for the chemical industry. For the textile industry the tax credit's costs exceeded its benefits, and for the pharmaceutaical iondustry the tax allowance's costs exceeded its benefits.
