Abstract:
The neoliberal stabilization paradigm of interest rate hikes and austerity left economies around the world unprepared for the shocks to essentials experienced in the overlapping emergencies of war, conflict, climate change, and pandemic. This presents a window of opportunity for a paradigm shift. Neoliberalism became hegemonic through stabilization policy. Post-neoliberalism will require an alternative stabilization paradigm. In this paper we revisit the classic reasoning for buffer stocks by Keynes, Kaldor, Graham, and others as a starting point for this paradigmatic shift. At the core of the neoliberal stabilization paradigm are the assumptions that competitive markets are efficient and that relative price changes ought to be separated from macro-outcomes. In contrast, buffer stock reasoning starts from the inherent instability and inefficiency of commodity markets. Price volatility in essential commodities can lead to sellers’ inflation because of the interaction with administered prices in the industrial sector and can hamper growth and development prospects. We illustrate that the buffer stock reasoning can help understand the 2020-2023 world food price crisis and propose a multi-layered buffer stock system for food staples as a steppingstone in a gradualist transition to post-neoliberalism and a tool for a green transformation of agriculture.

Abstract:
In the wake of the global energy crisis, many European countries used energy price controls to fight inflation and to stabilize the economy. Despite its wide adoption, many economists remained skeptical. In this paper, we argue that price controls should be part of the policy toolbox to respond to shocks to systemically important sectors because not using them can have large economic and political costs. We put forward our arguments in two steps. In a first step, we analyze the impact on the German economy and society of the global energy crisis that followed Russia’s attack on Ukraine in February 2022. Our analysis shows that energy shocks matter. Specifically, the one-year GDP loss of the energy crisis 2022 amounts to 4 percent and is of a comparable magnitude to the short-run output losses during the COVID-19 crisis 2020 and the global financial crisis 2008. In addition, during the energy crisis 2022 inflation rates rose dramatically and real wages dropped more than in any other year in post-war Germany. There are also clear signs that the crisis is causing severe long-term economic damage (hysteresis effects). At the beginning of 2024, GDP is 7 percent and real wages are 10 percent below their pre-COVID-19 trend. We argue that the German government handled the immediate response to the energy shock well, but subsequently waited too long to introduce an energy price brake in 2022. This failure to act decisively in response to heightened economic insecurity coincided with a strong rise of the approval rates of the far-right AfD in the summer of 2022. We also show that the German energy price brake was an effective price stabilization policy for households, but did not protect the industrial base appropriately making it more likely that the German economy will continue to stagnate. In a final step, we turn to the use of price controls as an optimal policy response to an energy shock within a general equilibrium framework. We develop a simple production model with an energy sector and shows that price controls are socially optimal whenever selffulfilling expectations generate endogenous price uncertainty in the wake of an energy shock. We also link our analysis to the so-called sunspot literature that was developed in the 1980s as a response to the rational-expectations revolution in macroeconomics. Finally, we use our theoretical analysis to shed some light on the economic policy debate and the resistance of German mainstream economists to the introduction of energy price controls in 2022.
