The Quadrilemma of a Small Open Circular Economy Through a Prism of the 9R Strategies

The Circular Economy (CE) challenges the traditional linear economy model to arrive at a sustainable economy that minimizes resource use, its negative environmental impact, and dependency on resource imports. We develop a multi-sector dynamic stochastic general equilibrium small open economy model with endogenous adoption of exogenous foreign technology innovations, endogenous environmental quality, and CE elements, comprising recyclable waste as well as recycling and refurbishing sectors. We analyze the model-implied impulse response functions with respect to several economic shocks and conduct a rich scenario-based analysis, for which the scenarios are derived from the 9R strategies. We find important trade-offs to be considered by the economy with respect to circularity, trade, environment, and growth – the four dimensions of the quadrilemma of a small open circular economy. We find that none of the six shocks considered and in none of the eight scenarios analyzed the quadrilemma can be resolved. However, a positive shock to the price of energy or a lower energy share in one of the two intermediate goods sectors provide benefits to three out of four dimensions of the quadrilemma.
