Modern money theory on fiscal and monetary policies: empirics, theory, and praxis

3 EXPLAINING THE STYLIZED FACTs
3.1 Endogenous fiscal balance and recessionary austerity
In order to explain the empirics, MMT does not rely on the mainstream theoretical work of the past 50 years, most of which is a step backward to the pre-1940s microeconomics/markets/imperfections way of analysing national issues. Instead, MMT-ers rely on the theoretical work and models developed by Keynes, post-Keynesian economists, 'old' institutional economists, among others, as well as their own (for example, Fullwiler 2007; Godley/Lavoie 2007a; Hein 2018; Wray et al. 2018). A central conclusion is that the fiscal balance is not under the control of policymakers but, rather, adapts to the needs of the economic system. Most government spending is not discretionary and tax revenues are heavily influenced by the state of the economy. While policymakers do set some spending (discretionary spending represents about 30 percent of the budget in the United States), do determine tax rates, and can make some predictions about total spending and tax revenues at the end of the year, they have no control over budgetary dynamics during the year. Like private aggregate saving, the fiscal balance is a residual outcome of the economic process and any attempt by the federal/national government to proactively influence the balance will most likely fail because the non-federal sector (state and local governments, the domestic private sector, and the foreign sector) desires to record a surplus. If the national government has a fiscal balance that is not consistent with the desire of the non-federal sector, national income will adjust upward or downward as sub-sets of the non-federal sector change their spending level. Automatic stabilizers will move the fiscal balance to the level desired by the non-federal sector. Reinhart/Rogoff (2009) argue that high public debt slows economic growth; instead, the business cycle drives public-debt dynamics (Nersisyan/Wray 2010).
The previous dynamics are complicated by the fact that policymakers may also want to reach a fiscal surplus (or a fiscal deficit that is less than the desired surplus of the non-federal sector) in order to show that the government is 'fiscally responsible.' Such austerity policy is recessionary and amplifies the business cycle, unless at least one sub-set of the non-federal sector is willing to deficit spend enough to counter the economic drag generated by fiscal austerity. However, deficit spending by the non-federal sector is prone to financial instability because its sub-sets lack monetary sovereignty and so are revenue constrained (Minsky 1986; Tymoigne/Wray 2014). As such, fiscal surpluses tend to be destabilizing. The self-defeating nature of fiscal austerity has gained some attention outside MMT following the 2008 Great Recession (DeLong/Summers 2012; Agnello et al. 2013; Fatás/Summers 2018).
On the contrary, fiscal deficits are sustainable because a monetarily sovereign government has the financial flexibility to meet the demands of such deficits. Monetary sovereignty gives one degree of freedom in the tight rules of national accounting. It allows the fiscal balance to accommodate the needs of the economy. Fiscal deficits help other sectors through three channels (Minsky 1983; 1986). First, fiscal deficits sustain national income by injecting more income into the economy than they remove through taxes. Fiscal deficits sustain private investment by stabilizing expected sales and capacity utilization – the main drivers of business investment – while having a negligible impact on interest rates. Second, they generate positive cash flows for other economic units. Third, they also have beneficial portfolio effects, because Treasuries are credit-risk free (the nominal debt service can always be paid on time in full), and liquid financial instruments that are a core staple of the financial system.
Thus, fiscal deficits tame financial crises, they do not lead to financial crises when monetary sovereignty prevails, because such government is always solvent in its own currency and because the liquidity and solvency of other sectors is improved. More broadly, governments have been a core element of economic strength as aggregate demand plays a central role for economic growth over time (Lavoie 2014; Tavani/Zamparelli 2017). Steindl (1952), Walker/Vatter (1989), and Vatter et al. (1995) show that fiscal policy has a crucial role to play to put the economy onto a higher growth path (Wray 2008). Government is also a major source of innovations that stimulates both public and private investments (Mazzucato 2015).
3.2 Monetary policy and transmission mechanisms
DP argue that MMT does not provide a monetary policy strategy, does not explain the transmission mechanics of monetary policy, and argue that a zero-rate policy is destabilizing. Once again, some models have been developed by MMT-ers and post-Keynesians to study the impact of a zero policy rate. For example, Tymoigne (2009) builds a stock–flow model to analyse the impact of different types of monetary policies and concludes that leaving the policy rate at zero is the most stabilizing policy. Rochon/Setterfield (2011: 132) study the impact of different monetary policy rules and show that a permanent zero central-bank rate 'always yields the highest rate of growth and the lowest rate of inflation.' More broadly, MMT rejects the relative price mechanics that are at the core of at least some mainstream models (Lavoie 2008).
MMT argues that monetary policy is not a reliable tool to manage inflation and economic growth because of its weak and potentially perverse effects (Papadimitriou/Wray 1994; 1996; 2021; Mitchell/Muysken 2008: 146ff). While some sectors are more sensitive to changes in interest rates, overall interest rates do not play a major role in determining aggregate spending, especially business investment (Fazzari et al. 1988; Fazzari 1993; Glyn 1997). This sensitivity declines as an economic expansion progresses, and gradualism and transparency have made it much easier to anticipate adverse changes in interest rates and to hedge against them. In addition, in a leveraged economy, economic units have to meet their financial commitments regardless of the level of interest rates. Higher interest rates mean higher financial commitments, which creates a potential need to ask for more credit to meet these commitments (Kregel 1992; Wray 1993; Mason/Jayadev 2014). Finally, interest rates may have a perverse effect on inflation through cost and demand channels. Higher interest rates raise operating costs and businesses may pass the additional costs onto their customers. Higher policy rates also boost the income of rentiers and raise their consumption (Lavoie 1995; Kelton/Wray 2006; Tauheed/Wray 2006; Tillmann 2008). Chairman Greenspan (Federal Open Market Committee 2000: 85), among others at the FOMC, recognized this possibility: 'There is deterioration in the inflation rate stemming from interest costs and energy costs, and those are not trivial sources of deterioration. At the end of the day it doesn't have to be labor costs that are causing the overall inflation deterioration.'
Most of the credit for price stability should be attributed to the taming of energy prices and the industrialization of China that flooded the world with cheap goods, together with a bit of luck (Stock/Watson 2002; 2005).May I remind you that we shouldn't take too much credit for the price easing? I never thought we were totally at fault for the price increases that we suffered from OPEC and food; and I don't think the fact that OPEC and food have calmed down has a great deal to do with monetary policy per se, except in the very long run.
While DP (2021: 358) argue that 'near-zero level would also foster macroeconomic instability,' MMT changes the way the central bank intervenes in the economy. Instead of trying to fine-tune the business cycle, central banks should refocus their operations and goals on the purpose for which most were created (Capie et al. 1994), namely ensuring an elastic currency for the economy (that is, reliable financing and refinancing channels for banks and the national Treasury) together with proactive regulation and supervision of the financial industry (instead of mere reactive regulation à la Basel Accords). MMT proponents advocate financial regulation and supervision along the lines of Minsky's theoretical framework; that means the promotion of safe underwriting, the establishment of a financial structure that promotes long-term recurring relationships between bankers and their clients, and the regulation of financial innovations toward safe financial products (that is, those that promote hedge financing) (Tymoigne 2011; Tymoigne/Wray 2014). Bank credit should be limited to creditworthy clients but banks should be encouraged to look for them wherever they are and to avoid redlining (Minsky et al. 1993). Credit controls and the routine provision of reserves through selective acceptance of securities at the Discount Window (Kregel 1992) should be used to restrict the flow of credit toward speculative endeavors, and to move that flow toward financially sustainable economic activities that are defined as 'good' by the public purpose.
4 MMT AND NATIONAL POLICYMAKING: PROMOTING SOUNDER POLICYMAKING PRAXIS
4.1 Financial praxis: many governments already 'do MMT'
MMT is a theory grounded in a detailed institutional analysis of monetary and fiscal operations of national governments. It describes what goes on behind the curtain in terms of the financial operations of national governments. Throughout the world, national governments routinely rely on a heavy coordination of their fiscal and monetary branches to ensure smooth government financial operations. DP (2021: 356) argue incorrectly that 'MMT never explains what "coordination" entails'; there is a large body of work on the topic (Sundararajan et al. 1997; Wray 1998; Bell 2000; Mitchell/Mosler 2002; Silva/Richard 2010; Tymoigne 2014; Vajs 2014; Allen 2019; Lavoie 2019). The financial operations of the Treasury and the central bank of monetarily sovereign governments are so intertwined that both of them are constantly in contact to make fiscal and monetary policies run smoothly. The Treasury routinely helps in monetary policy operations. The central bank routinely helps finance the Treasury. There is nothing inflationary about that, it just ensures that the Treasury has enough funds to implement the budget passed by Congress. The pace and composition of spending set in the budget are what could be inflationary, not the fact that the bank accounts of the Treasury are well provisioned nor that the provisioning of such accounts is done through keystrokes.
This institutional analysis leads to three main points, one theoretical, one practical, and one institutional. The theoretical point that MMT extracts from the institutional analysis of monetarily sovereign governments is that government finance is not scarce, as long as a national government spends on goods and services priced in the domestic currency (which may be broader or narrower than the goods and services produced domestically). There is no such thing as a fixed supply of saving against which the government must compete with the private sector. In addition, household, business, state, and local government finances are incorrect reference points to understand national public finances when monetary sovereignty prevails. A monetarily sovereign government is the issuer of the domestic currency, whereas others are users of such currency. Finally, the effects of the complex interactions between the central bank and the Treasury can be captured by merging these two government entities into one (a national government that issues the domestic currency, and taxes and issues securities to destroy the currency). This common theoretical (and rhetorical) tool is a good first approximation of the financial praxis of monetarily sovereign governments.
The institutional point is that implementing MMT policymaking does not require radical changes in the way the Treasury and the central bank interact today. DP confuse a theoretical tool (consolidated government) with policy prescriptions they wrongly attribute to MMT (monetizing the public debt, quantitative easing, fiscal dominance). No change in existing government finances is necessary because national Treasuries and central banks all over the world already routinely work together. While the central bank has independence of tools and goals, it must account for the needs of the Treasury in a monetarily sovereign government (MacLaury 1977; Wray 2007; 2014; Felipe et al. 2020). Central-bank involvement in public finances is an old and routine practice. While suspicion about such involvement has changed the way that involvement has happened over time, it has not eliminated such involvement (Tymoigne 2014; Garbade 2019). In addition, allowing direct financing of the Treasury is not a radical step, as it is already in place in some countries and is commonly used in Canada today (Jácome et al. 2012; Juniper et al. 2014; Lavoie 2019). MMT just points out that the layers of institutional complexity that hide this routine coordination are unnecessary and confuse the policymaking praxis. This coordination may as well be simplified but that is not a necessity and allowing direct financing (or implementing quantitative easing (Fullwiler/Wray 2010)) does not mean practicing MMT policymaking.
The practical point that MMT extracts from the institutional analysis is that, if monetary sovereignty prevails, policymaking must be reframed around the limits and opportunities that comes with monetary sovereignty. Fiscal deficits are not intrinsically worrisome; fiscal surpluses are not to be celebrated and do not give any 'breathing room' to spend. As long as government is operating within its domestic monetary system, government spending and tax policy ought to be set independently without regard for the impact on the fiscal position, but with regard to the impact on the domestic economy including inflation.
4.2 Policymaking praxis: monetarily sovereign governments do not 'do MMT'
While the financial praxis of monetarily sovereign governments is integrated into the MMT framework, the policymaking praxis of these governments does not reflect MMT policymaking principles. Instead, policymaking is dominated by deficit hawks and deficit doves who want to have some form of austerity commitment by the national government. MMT-ers are deficit owls, they argue that austerity commitments are unnecessary and counter-productive; the fiscal balance self-corrects to an equilibrium position, usually a deficit. Instead of putting the national budget and public debt at the center of policymaking, MMT puts actual economic goals (full employment, price stability, environmental sustainability, etc.) there. In addition, MMT wants to rationalize the discussions about the national budget by dealing with two unproductive aspects of current budgetary procedures, the fearmongering about the 'road to ruin' and the absurdity of the 'pay-for' logic.
When monetary sovereignty is understood, it is pointless for policymakers to seek to put funds in a locked box for later use, to modify existing domestic programs, or to conceive new domestic programs to help save money in order to avoid insolvency. The funds needed are created quickly, as emergency spending to fight wars or deal with pandemics shows, and insolvency is not financially possible. The fact that finance is not scarce when monetary sovereignty exists does not imply that the government can, or should, spend a lot more, nor does it mean that policymakers will ramp up spending quickly in a chaotic manner as the experiences of most monetarily sovereign governments show. This does not mean that government mismanagements cannot occur or that MMT denies past cases of hyper-inflation. In line with its theory of inflation, MMT has a non-monetary explanation of hyper-inflation (Tymoigne 2023). In addition, policies to fight inflationary pressures ought not to be ad hoc (for example by raising tax rates in reaction to price instability), but, rather, should be established through structural programs that tackle different sources of potential inflation over the long term (strong automatic stabilizers, efficiency standards, energy policy, tax structure, job-guarantee programs, and price controls, among others).
The absence of financial constraints does not mean that creating a budget is unnecessary and that the fiscal space is 'limitless' (DP 2021: 357). MMT emphasizes that budgetary procedures are political in nature, and the point is to promote procedures that encourage rational discussions, accountability, and transparency in policymaking. While setting up a budget, policymakers must tackle two constraints. On the political side, a society must decide, hopefully as democratically as possible, what the public purpose is: What should the government do? And how should it do it? On the economic side, a policy proposal needs to be judged by its economic feasibility, not only in absolute terms but also relative to other proposals. Governmental bodies such as the Congressional Budget Office (CBO) should score projects based on what is possible given the available human, natural, and physical resources, and should determine the pace at which a proposal can be implemented realistically given the current and expected state of domestic resources. If resources are not available or cannot be made available, a proposal ought not to be approved even though it can easily be financed by keystroking numbers in accounts. This method of judging a policy proposal is far superior to the current way the CBO judges a proposal, which merely consists of checking whether it will add to the public debt or not. If the government is not monetarily sovereign, a financial constraint further limits what the government can do and an eye should be kept on balancing the government budget and limiting automatic stabilizers; however, that comes at the cost of more economic instability and less ability to tackle the major contemporary issues (Wray 2003; Godley/Lavoie 2007b).
