A tale of two growth engines: The interactive effects of monetary policy and intellectual property rights

How do intellectual property rights that determine the market power of firms influence the effects of monetary policy on economic growth and social welfare? To analyze this question, we develop a monetary R&D-based growth model with elastic labor supply. We find that monetary expansion reduces growth and welfare through a decrease in labor supply that reduces R&D. Furthermore, a larger market power of firms strengthens these effects of monetary policy in the R&D model. In contrast, increasing the market power of firms dampens the growth and welfare effects of monetary policy in the AK model. Therefore, the market power of firms has drastically different implications on the welfare cost of inflation under the two growth engines (i.e., innovation versus capital accumulation). We also calibrate the two models using data in the US and the Euro Area to quantitatively evaluate and compare the welfare cost of inflation in the two economies. Finally, we simulate transition dynamics of the R&D model in order to compute the complete welfare changes from reducing inflation

Search and endogenous growth: when Romer meets Lagos and Wright

In this note, we develop a search-based monetary growth model to analyze the growth and welfare effects of inflation. We introduce endogenous growth via capital externality into a two-sector search model and compare the effects of inflation to those from a standard cash-in-advance (CIA) growth model. We �find two important differences between the two approaches. First, while the growth effect of inflation operates solely through endogenous labor supply in the CIA model, the growth effect of inflation operates through an additional consumption effect in the decentralized market in the search model. Second, we quantitatively evaluate the welfare cost of inflation and fi�nd that the search model exhibits a larger (smaller) welfare gain than the CIA model when we decrease the growth rate of money supply to achieve the Friedman rule (zero inflation). These contrasting results are due to a non-linearity in welfare as a function of inflation in the search model

A tale of two growth engines: Interactive effects of monetary policy and intellectual property rights

How do intellectual property rights that determine the market power of firms influence the growth and welfare effects of monetary policy? To analyze this question, we develop a monetary endogenous-growth model in which R&D and capital accumulation are both engines of long-run economic growth. We find that monetary expansion hurts economic growth and social welfare by reducing R&D and capital accumulation. Furthermore, a larger market power of firms strengthens these growth and welfare effects of monetary policy through the R&D channel but weakens these effects through the capital-accumulation channel. Therefore, whether the market power of firms amplifies or mitigates the welfare cost of inflation depends on the relative importance of the two growth engines. Finally, we calibrate the model using data in the United States and the Euro Area to quantitatively evaluate and compare the welfare cost of inflation in these two economies and find that the R&D channel dominates in both economies

Money and random matching in an endogenous growth model

In this study, we develop a search-based monetary growth model to analyze the effects of inflation on economic growth and social welfare by introducing endogenous economic growth via capital externality into a two-sector search model. We �find that the channel through which inflation affects economic growth in the search model is different from the cash-in-advance model. In the quantitative analysis, we evaluate the welfare effect of inflation in the search-based endogenous growth model and compare it to a search-based exogenous growth model. We �find that the welfare effect of inflation is nonlinear in the endogenous growth model whereas it is linear in the exogenous growth model. Furthermore, we find that the welfare cost of inflation under endogenous growth is about three times as large as the welfare cost under exogenous growth

A Tale of Two Growth Engines: Interactive Effects of Monetary Policy and Intellectual Property Rights

How do intellectual property rights that determine the market power of firms influence the effects of monetary policy? In a hybrid endogenous growth model in which R&D and capital accumulation are both engines of long-run economic growth, we find that monetary expansion hurts economic growth and social welfare by reducing R&D and capital accumulation. Furthermore, a larger market power of firms strengthens (weakens) these effects through the R&D (capital-accumulation) channel. Finally, we calibrate the model using data in the US and Euro Area to simulate the welfare cost of inflation and find that the R&D channel dominates in both economies

Money, Random Matching and Endogenous Growth: A Quantitative Analysis

In this study, we develop a search-and-matching monetary growth model to analyze the effects of inflation on economic growth and social welfare by introducing endogenous economic growth via capital externality into a two-sector search-and-matching model. We find that the channel through which inflation affects economic growth in the search-and-matching model is different from the traditional cash-in-advance model. To facilitate the calibration, we obtain an empirical estimate of the effects of inflation on economic growth using panel regressions. In the simulation analysis, we quantitatively evaluate the welfare effect of inflation in the search-and-matching endogenous growth model and compare it to a search-and-matching exogenous growth model. We find that the welfare effect of inflation is nonlinear in the endogenous growth model whereas it is linear in the exogenous growth model. Furthermore, we find that the welfare cost of inflation under endogenous growth is up to four times as large as the welfare cost of inflation under exogenous growth
