Environmental amenities and optimal agricultural land use: The case of Israel

This paper evaluates the effectiveness of changing land allocation among crops as a mechanism for increasing net-social benefits, where production profits and amenity values are augmented. A positive mathematical programming model is calibrated and applied to 43 regions in the northern part of Israel, using a crop-discriminating amenity-value function. Changes in land allocation increase net-social benefits by 2.4% nationwide and by up to 15% on the regional level, where in some regions the net-social-benefits-increase/profit-loss ratio exceeds 20. Therefore, the results indicate that a policy encouraging amenity-enhancement of agricultural land use is warranted, provided that it is implemented on a regional scale, rather than as a comprehensive nationwide-enforced program.

Employee involvement climate,task and citizenship performance,and instability as a moderator

This study explored the group-level effects of a climate of employee involvement. Using the immediate manager as the referent, we examined data from 153 workgroups to establish a positive relationship between climate for employee involvement and performance. Through multilevel analysis, we provide results supporting that a climate for employee involvement positively relates to group citizenship behaviors and group task performance, respectively. Furthermore, moderation analyses confirmed the deleterious effects of member turnover on the positive relationship between a climate of employee involvement and performance. Taken together, these results support the concurrent work exploring transactive memory and mental models in groups to further explicate the interactive effects of group-level perceptions and stability on performance.     

The Fed's Communications: Suggestions for Improvement

The chief economist of Berenberg Capital Markets proposes three broad ways of improving the Fed's communications: (1) establish a more systematic approach to achieving its dual mandate; (2) clarify the proper role of monetary policy in achieving those objectives by distinguishing what is within the scope of monetary policy from what is clearly beyond it; and (3) articulate the Fed's goals and role in achieving macro‐prudential risk management and financial stability. With these three ends in view, the author begins by urging FOMC members to refrain from making public comments immediately following government data releases and, when making public speeches and statements, to relate their comments on the economy to the Fed's dual mandate. The author also suggests three modifications of the Fed's official Policy Statement following FOMC meetings. First, each statement should start with an assessment of monetary policy and its consistency with achieving the Fed's statutory mandate, rather than the Fed's assessments of the economy and its subsectors with which such statements now begin. Second, the Fed should communicate separate explicit risk assessments of inflation and of the prospects for employment and the economy. (The Fed's current practice of sometimes dropping the risk assessments from statements and replacing them with nuanced language—for example, on changes in inflation and inflationary expectations—can be a source of confusion.) Third, all statements should discuss as clearly as possible the Fed's strategy for its balance sheet and unwind policy. The Fed's quarterly Summary of Economic Projections (SEPs) should be redesigned to include FOMC estimates of forecast uncertainties and what they imply for monetary policy, and such alternative forecasts should be presented in place of the current central tendency and range of forecasts. The redesigned SEPs should be (1) based on a rigorous Fed assessment of expected monetary policy under different situations and contingency planning, and (2) as transparent as possible about the Fed's economic and inflation outlooks, the uncertainties in forecasting, and the conditionality of monetary policy. An illustration is provided of the alternative SEPs that would replace the current “dot plots” and include the Fed's forecasts of nominal GDP, calculated confidence intervals around the FOMC's median forecasts, and three separate forecasts of the Fed's perceived appropriate Fed funds rate. Finally, the author views the “optimal solution” as a more systematic approach in which the Fed publishes a single forecast based on a model consistent with its dual mandate that shows how the appropriate Fed funds rate path would be expected to vary under different economic and inflation outcomes. Such an approach, by thus mapping likely monetary policy responses to alternative plausible economic and inflation outcomes, would increase the Fed's accountability as well as its transparency.     

Do enlarged fiscal deficits cause inflation? The historical record

We survey the historical record for two centuries on the connection between expansionary fiscal policy and inflation. The relationship holds in wartime when fiscally stressed governments resorted to the inflation tax. In two peacetime episodes in the early twentieth century, bond‐financed fiscal deficits, unbacked by future taxes, may have contributed to inflation. Fiscal influence on monetary policy was important in the Great Inflation 1965–1983. Expansionary monetary and fiscal policy did not lead to inflation in the Global Financial Crisis of 2007–08 but, by contrast, the fiscal and monetary response to the COVID‐19 pandemic may involve risks of fiscal dominance and future inflation.     

Factors affecting monetary policy in an era of inflation

A money supply-reaction function is developed and estimated within the context of an IS-LM framework to test the responsiveness of the Federal Reserve to the government budget restraint and certain parameters of the model. The results reveal that a large portion of the recent expansion of the monetary base may be attributed to increases in government debt and provide an essential first step in quantifying the inflationary impact of deficits. The monetary base is also expanded in response to increases in inflationary expectations and previous increases in the monetary base, but is not statistically correlated to changes in the unemployment rate or potential national income, or to rises in interest rates caused by sources other than higher inflationary expectations, previous monetary policy, or the Treasury borrowing requirement.     

Start-ups as drivers of market mobility: an analysis at the region–sector level for The Netherlands

Although recent literature suggests that competition among incumbent firms is caused by the entry of new firms, this relationship has not yet been tested directly. In this study a regression model is established in which a direct measure of competition among incumbent firms, the market mobility rate, is explained by start-up rates and control variables. The results show that the effect of start-ups on market mobility varies by sector. There is a strong positive relationship for industry sectors but an insignificant relationship for service sectors. These results suggest differences in the types of entry between sectors and in the roles start-ups play in different sectors.     

The necessity for a strategic approach to monetary policy

The Fed has a spotty track record, and its discretionary approach to conducting monetary policy will lead to the same mistakes it made in the past. I emphasize the importance of adopting a strategic framework for conducting monetary policy. The Fed has constantly changed the course of monetary policy in response to high-frequency data and other temporary factors. The Fed’s excessive monetary ease has distorted economic and financial behavior. The Fed should base its policy on longer-run objectives rather than short-run economic and financial fluctuations, and communicate these objectives to the public and to financial markets. Under the Financial Choice Act, the Fed would have to establish a strategic guideline, and explain to Congress why monetary policy may be deviating from the guideline. I respect the Fed and see the need for change to maintain its credibility. The Fed must acknowledge its shortfalls and modify its focus.     

The changing status of economic minorities, 1948–1977

Conclusion Our results indicate that the median income of economic minorities relative to that of whites does not adequately represent the entire income distribution. Among black males, for example, only the lower half of the income distribution experiences a significant change in relative income over the business cycle. The secular trend shows similar variation. Black men at the 25th, 50th, and 75th percentiles experienced significant gains relative to whites in the 1965–77 period while there was little improvement among blacks in the 90th percentile. Using a measure of central tendency to generalize about the entire distribution of an economic minority is a dubious proposition. While this may seem like a trival point, it should be remembered that in today’s political climate such credence is being given to improvement in the general health of the economy as the best way to foster economic progress for economic minorities, while less general remedies, such as affirmative action, are rapidly being deemphasized.
