Circular economy today represents a pivotal concept in the development of production methods capable of combining sustainability, innovation and value creation. The commitment of companies to implement the transition to circular operating models requires new knowledge, skills, models and tools, through which to develop innovative solutions capable of generating value starting from production waste. The course promotes an adequate understanding of how the circular economy can be applied in companies, starting from the definition of the strategic approach up to the operational implementation through the design of products, the acquisition of key skills, the development of specific technologies and measurement of circularity at company and product level. The course allows to acquire advanced theoretical knowledge of circular economy, fundamental for the correct evaluation of opportunities and implications in business and to develop skills, skills and tools necessary to create new business models based on the principles of Circular Economy. The program is divided into four parts. Part I: Theory of the firm and demand - Analysis of the technology: production function, technical properties of isoquants - Definition and characteristics of the marginal productivity of the factors - Definition and characteristics of returns to scale - Analysis of some examples of technology: Leontief, input perfect substitutes, Cobb-Douglas - Formalization of the problem of the choice of the firm: the problem of profit maximization in the short and in the long run, the demand functions of the inputs and the supply function of the company - The problem of minimization of costs in the long and the short term: the conditioning of the input demand functions and the function of the total cost - Cost curves undertaking 's in the long run: average cost and marginal cost, returns to scale and trend of costs in the long run - The cost curves in the short term: fixed costs and variable costs, average cost and marginal cost, the performance of short-term costs and marginal returns of the factors - The supply function in the long-and short-term: optimal condition for the 'enterprise in the long-and short-term - Individual demand and market demand - Inverse demand function - Elasticity, elasticity and demand elasticity and revenue, marginal elasticity ericavo - Marginal revenue - Income elasticity Part II: Econometric Test on optimizing behavior - Hypothesis optimization - Test the behavior of nonparametric maximization - Test the behavior of parametric maximization - Restrictions imposed by 'optimization - Quality of adaptation of optimization models - Structural models and reduced form models - Estimate of the technological relationships - Estimate of the questions of the factors - Technologies more complex - Choice of functional form Part III: Budget, costs, investments - Introduction to the financial statements, balance sheet, income statement - Accounting systems, revenue, inventory and cost of goods sold - Fixed assets, depreciation, Liabilities, and Equity - Budget Analysis - Classification of costs, contribution margin and full costs - Decision of short-term and investment analysis - Measurement of performance
