Ran Abramitzky's book, The Mystery of the Kibbutz: Egalitarian Principles in a Capitalist World, tries to answer the questions of why the communal kibbutz worked so well in Israel's formative years and what limits its current success in modern Israel. Initial ideological commitment and the special circumstances of Israel's founding led to unusual success when combined with well-thought-out rules on behavior and entry. Over time, the commitment to socialistic income sharing has not worked so well, given modern technology and global commerce. The author links up these ideas to the broader issue of organizational structure but misses out on some opportunities to test the ideas further. (JEL D31, D63, D82, J24, P13, Q13)

This article reviews the history of race laws in the United States as distinct from the rule of law, an idea found in the writing and speeches of Sadie Tanner Mossell Alexander, the first African American PhD in economics (1921). We review the race laws of slavery, lynching, Negro Jobs, and the making of the Black ghetto. We highlight the life and writings of Alexander and other early African American economists as an example of the cost of racial exclusion in the economics profession and how it has impeded the production of useful knowledge about the workings of the US economy.

Productive public good investment allocations, and group discriminatory redistributions are conflicting resource use options between which every government must choose irrespective of its political make up. This paper is the first to derive an incisive explanation of how governments combine political and economic calculation to balance these competing choices. Realistic societies can be analyzed as a mixture of two polar cases — idealized, utopian, consensual democracy and perfect autocracy. Thus, in making the choice between social investment and redistributive taxation every government behaves somewhat like an pure democracy and somewhat like a selfish dictatorship.

Following George Stigler (1964), many economists assume that incentive problems undermine attempts b firms to collude to raise prices and restrict output. But the potential profits from collusion can create a powerful incentive as well. Theory cannot tell us, a priori, which effect will dominate: whether or when cartels succeed is thus an empirical question. We examine a wide variety of empirical studies of cartels to answer the following questions: (1) Can cartels succeed? (2) If so, for how long? (3) What impact do cartels have? (4) What causes cartels to break up? We conclude that many cartels do survive, and that the distribution of duration is bimodal. While the average duration of cartels across a range of studies is about five years, many cartels break up very quickly (i.e., in less than a year). But there are many others that last between five and ten years, and some that last decades. Limited evidence suggests that cartels are able to increase prices and profits, to varying degrees. Cartels can also affect other non-price variables, including advertising, innovation, investment, barriers to entry, and concentration. Cartels break up occasionally because of cheating or lack of effective monitoring, but the biggest challenges cartels face are entry and adjustment of the collusive agreement in response to changing economic conditions. Cartels that develop organizational structures that allow them the flexibility to respond to these changing conditions are more likely to survive. Price wars that erupt are often the result of bargaining issues that arise in such circumstances. Sophisticated cartel organizations are also able to develop multipronged strategies to monitor one another to deter cheating and a variety of interventions to increase barriers to entry.

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivates this paradigm shift. The renewed interest in hysteresis (or “scarring” in recent parlance) has been sparked by the persistent impact of the global financial crisis —as GDP in advanced economies remained far below the precrisis trends for over a decade—and recent concerns about the lasting impact of the COVID-19 shock. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects. (JEL E22, E23, E24, E32, E63, G01, O41)

In nursing this essay through several drafts, I have benefited greatly from suggestions by Edward Denison, Robert Evenson, Zvi Griliches, Richard Levin, John Kendrick, Edwin Mansfield, and Richard Murnane. Moses Abramovitz has been a source ofencouragement and good, substantive editorial advice, for which I am most grateful. The heterodox views are my own, although I share many of them with Sidney Winter.

To evaluate early embryo development, 248 good to excellent bovine morulae were cultured in Ham's F-10 medium, supplemented with 10% steer serum, uterine flushings from Days 6, 10 or 15 following estrus (0.01, 0.1, 1.0 and 10% protein; 64 mg protein/ml), and 1.0% uterine flushings and 10% steer serum. Final development scores for embryos in steer serum were significantly higher (range across experiments was: 4.06 to 4.37) than for embryos cultured in uterine flushings alone (-0.23 to 0.52). Treatment means were not different (P >0.05) when 10% steer serum was added to 1.0% uterine flushings. A higher percentage of embryos in 10% steer serum (92%) than in 10% steer serum plus 1.0% uterine flushing from Day 6 (33%), Day 10 (45%) and Day 15 (50%) developed to hatched blastocysts. Embryos cultured in 1.0% Day 6 uterine flushings plus 10% steer serum required more time to attain the early blastocyst and blastocyst stages, while embryos in 1.0% Day 15 uterine flushings and 10% steer serum developed at the same rate as controls to the expanded blastocyst stage, but hatched sooner (72.8 vs 96.5 h). These results suggest substance(s) in uterine secretions can have inhibitory and stimulatory influences on early bovine embryo development.
