Transition towards and of sustainability—Understanding sustainability as performative

Our purpose is to explore the concept of “sustainability” when understood from a performative perspective, i.e. as a concept that is filled with meaning across time. Drawing on a 10 year-long study of the digital footprint of Stockholm Royal Seaport, claimed to be northern Europe's largest sustainable urban development district, we show that “sustainability” emerged as the project became associated with particular places, projects, histories, and technologies. This means that “sustainability” was local in that it was situated in the particular spatial context of the project; temporal in that it was situated in a particular time; and political in that it expressed particular values and perspectives. The study contributes to explaining why “sustainability” remains—and always will remain—a contested concept, which is why sustainability transitions are complex. Consequently, we suggest that the transition towards sustainability always involves the transition of sustainability, something that needs to be acknowledged in order for a transition to actually become sustainable.     

Henry George and the Institution of Private Property in Land: A Property Rights Approach

Abstract . Conflicting statements concerning whether the implementation of Henry George's single tax proposal would destroy the institution of private property in land have appeared in the literatures of economics and other disciplines. A number of writers have implied that the taxation of Ricardian rent is equivalent to land nationalization. In the main, followers of George have denied that the single tax would abolish private property in land. Their claim is based on the fact that land titles would remain in private hands under the single tax. Since the whole question of private property is beset with ideological difficulties, a property rights approach is applied to this issue in an attempt to resolve the controversy. The conclusions are that the actual implementation of George's system would not destroy private property in land and that it is incorrect to equate the single tax with land nationalization.     

R&D Cuts and Subsequent Reversals: Meeting or Beating Quarterly Analyst Forecasts

Abstract

Among firms that meet or beat earnings expectations, we find that cuts to R&D spending are more prevalent in Q4 relative to other interim quarters. This is consistent with the relative costs of real-activities management (accruals-based earnings management) decreasing (increasing) in Q4 due to the annual audit. More importantly, we find that the subsequent reversal of such R&D cuts is more prevalent and economically more significant following Q4 cuts relative to the reversals that follow cuts in other interim quarters. Our findings suggest that examination at the quarterly level (rather than annual level) lends new insights into the current debate regarding the prevalence of potentially value-destroying R&D cuts that managers make. Indeed, our findings suggest that some cuts may merely be temporary deferrals of R&D outlays.     

Sources of the great moderation: A time-series analysis of GDP subsectors

Recent work finds evidence that the volatility of the U.S. economy fell dramatically around the first quarter of 1984. We trace the timing of this so-called “Great Moderation” across many subsectors of the economy in order to better understand its root cause. We find that the interest rate sensitive sectors generally experience a much earlier volatility decline than other large sectors of the economy. The changes in Federal Reserve stabilization policies that occurred during the early 1980s support the view that an improved monetary policy played an important role in stabilizing real economic activity. We find only mild evidence that “good luck” was important and little evidence to support the claim that improved inventory management was important.     

Making unilateral trade liberalisation beneficial to the poor

In this paper, we investigate the impacts of unilateral import liberalisation by a representative South Asian developing economy, Nepal, and demonstrate those conditions required to make the impacts ‘pro-poor.’ Applying the Computable General Equilibrium model to Social Accounting Matrix data, we conclude that import liberalisation is growth-enhancing but that, unfortunately, the rich benefit more than do the poor. We envisage a restructured but plausible model economy that requires a transformational period of ten years, and simulate unilateral trade liberalisation but, in the context of a dynamic model. We conclude that improvement in efficiency parameters, reorganisation of investment patterns, along with reallocation of factors of production by both household group and activity type are required to make growth accrued by import liberalisation ‘pro-poor’ in developing economies such as that of Nepal.     

Spurious Fixed Effects Regression*

This article shows that spurious regression results can occur for a fixed effects model with weak time series variation in the regressor and/or strong time series variation in the regression errors when the first‐differenced and Within‐OLS estimators are used. Asymptotic properties of these estimators and the related t‐tests and model selection criteria are studied by sending the number of cross‐sectional observations to infinity. This article shows that the first‐differenced and Within‐OLS estimators diverge in probability, that the related t‐tests are inconsistent, that R²s converge to zero in probability and that AIC and BIC diverge to ?∞ in probability. The results of the article warn that one should not jump to the use of fixed effects regressions without considering the degree of time series variations in the data.     

Structural vs. atheoretic approaches to econometrics

In this paper I attempt to lay out the sources of conflict between the so-called “structural” and “experimentalist” camps in econometrics. Critics of the structural approach often assert that it produces results that rely on too many assumptions to be credible, and that the experimentalist approach provides an alternative that relies on fewer assumptions. Here, I argue that this is a false dichotomy. All econometric work relies heavily on a priori assumptions. The main difference between structural and experimental (or “atheoretic”) approaches is not in the number of assumptions but the extent to which they are made explicit.     

The proportion of blocking coalitions in atomless economies

In this paper we investigate the number of coalitions that block a given non-competitive allocation. In an atomless economy with a finite number of types we identify coalition with its profile. Considering profiles π that represent coalitions with the same proportions of types as in the whole society, we prove that there is a ball B_π with π as its center so that ‘almost half’ of the profiles in B_π are blocking. This result is an analogous result to that of Mas-Colell (1978) who dealt with large finite markets.     

WHAT HAPPENS AFTER SUCCESS: THE PERILS OF EXCELLENCE*

This article examines how past performance influences the way an organization evolves, makes decisions, and adapts to its environment. It argues that compared to other periods of history, those that follow a lengthy interval of success will reveal companies that are especially apt to: (1) exhibit inertia in many aspects of structure and strategy-making process; (2) pursue immoderation, that is, adopt extreme process orientations; (3) manifest inattention, that is, reduce intelligence gathering and information processing activity; and (4) demonstrate insularity by failing to adapt to changes in the environment. an empirical analysis of the long-term histories of 36 companies provides tentative support for these notions.     

Property Tax Assessment Reform: A Source of Local Revenue Windfall or Fiscal Retrenchment

Abstract . Researchers, state officials and taxpayers have often speculated that property tax assessment reform would lead to an increase in the overall tax burden. They contend that, given the large non-discretionary increase in the tax base during the reform, local governments can raise more resources without increasing the nominal tax rate. An empirical analysis of 74 towns in New York supports that position. However, two types of tax shifts that occurred in the wake of reassessment—interclass shifts of tax burden to the owners of residential propertieskovn the other property classes and intra-class shifts observed among residential property owners—have caused significant moderation in this pattern of local government behavior. Therefore, tax reform, while it bestows revenue windfalls upon some local governments, may require fiscal retrenchment by others.     

Growth and social capital: an evolutionary model

In this paper, we analyze the role of cooperation between firms through a model of growth and social capital. In a growth model à la Solow we incorporate the set of resources that a relational network has at its disposals, as a distinct production factor, and thus examine its dissemination through evolutionary type processes in firm interactions. Dynamic analysis of the model demonstrates that cooperation is able to increase the productivity of factors, fostering a higher rate of growth in the long term. The most significant result is that scarcity of social capital can produce a general collapse of the economic system in areas in which long term growth is usually sustained by the learning by doing and spillover of knowledge phenomena. This conclusion leads to reconsider the role of local development economic policies that should concentrate on activities that promote repeated interaction between firms proven to be cooperative or that encourage the formation of technological consortia.     

Can indeterminacy resolve the cross-country correlation puzzle?

Are productivity shocks the only driving force of international business fluctuations? In this paper I argue that another source of uncertainty—changes in market expectations or ‘sunspots’ – is also important. One major shortcoming of existing IRBC models is the ‘cross-country correlation puzzle’: models tend to generate cross-country consumption correlations that are too high and output, investment and employment correlations that are too low when compared to the data. I show that with empirically supported level of increasing returns, an otherwise standard model possesses multiple, indeterminate convergent paths to the steady state, which allow for sunspots to influence the economy. The model displays time series properties that in many ways match the data better than the conventional model. It is especially successful in generating realistic consumption and output correlations.     

The Negative Effects of Inappropriate Price Stimulation; The Case of Senegal: Rice Price Increases to Encourage Production May Harm Families of Non-responsive Subsistence Farmers

Abstract . Some governments of developing economieshzve been encouraged to use pricing policy to stimulate increases in food production. It is not known whether all subsistence farmers in those countries operate in an economic, financial and technological environment in which they can respond positively to price increases. In this paper models were used to demonstrate two situations: one in which farmers responded to price stimulation and another where price increases were ineffective, costly and produced results inconsistent with national goals. Data from the Basse Casamance Region in Senegal were used to show that farmers were not responsive to price changes and were net purchasers of grains. The study concludes that unless farmers' supply curves were shifted to the right—that is, that they meet more of their own subsistence needs—recent Senegalese government rice price increases could be harmful to the farm family.     

A decomposition of trends in U.S. consumer expenditures on communications and travel: 1984–2002

This paper offers a conceptual and partly empirical decomposition of the trends in U.S. consumer expenditures on five communications and nine transportation subcategories between 1984 and 2002. We find that inflation nearly always increases unit prices. Income effects are positive for all categories, meaning that these are all normal goods, not inferior ones. We speculate that taste changes have contributed to increasing expenditures in most categories, with the exception of out-of-town lodging, the public transit component of the public transportation category, and the old communication media categories of postage and reading. We suggest that production and technological changes have led to decreased unit prices in most categories. In the private vehicle operations categories, technological improvements dominate, so that expenditure shares have been decreasing despite increasing demand. Conversely, in the new media categories, taste changes dominate, so that expenditure shares are increasing despite technological improvements which lower prices. The decomposition explored here enhances our understanding of these important expenditure categories, and provides a useful methodology with which to examine trends in other categories as well.     

On Limits of Uniquely Best Linear Estimators

In a general linear model, it is shown that all admissible linear estimators are limits of linear estimators that are uniquely best at some point in an extended parameter set. The principal result shows that a linear estimator that is uniquely best at a pointW ₂ among multiple linear estimators that are best at a pointW ₁ is the limit of uniquely best estimators at points approachingW ₁ along the line joiningW ₁ andW ₂.

Muhammad's Conception of Property as A Bundle of Rights

Property was first conceived of as a bundle of rights in early Islam. The legal instrument that crystallised this Islamic conception was the waqf, a legal entity delivering public welfare in accordance with the wishes of a benefactor. Trusts, which evolved in the thirteenth century, have a rationale analogous to that of waqfs, and in fact may have replicated the legal template of waqfs. The finding that waqfs are germane to Islam has ramifications for policies on waqfs in contemporary Islamic societies.     

ADAM SMITH AND THE ROLE OF THE METAPHOR OF AN INVISIBLE HAND

Daniel Klein and Brandon Lucas's ‘In a Word or Two, Placed in the Middle: The Invisible Hand in Smith's Tomes’, following a vague hint by Peter Minowitz (2004) , offers original physical evidence that Smith ‘deliberately placed the phrase “led by an invisible hand”– at the physical centre of both his masterworks’. Further, it suggests that the invisible‐hand paragraphs are a response to Rousseau (1755 ); and that in ‘numerous and rich ways’, centrality holds ‘special and positive significance in Smith's thought’. This paper acknowledges the physical centrality of the invisible‐hand metaphor, but questions whether centrality alone gives weight to wider claims that the ‘invisible hand’ was Smith's ‘central idea’. It draws upon Smith's Rhetoric Lectures (1763), and argues that the invisible‐hand paragraphs in The Theory of Moral Sentiments and Wealth of Nations identify the actual objects of the invisible‐hand metaphor. This paper insists that Adam Smith is the most reliable source for revealing what he meant. In contrast, most modern attributions of special meaning to Adam Smith's use of the metaphor ignore Smith's teaching on the use of metaphors and, instead, make numerous, and often mutually exclusive, claims that Smith had a ‘doctrine’ of ‘an invisible‐hand’.     

Aggregate stock market behavior and investors’ low risk aversion

This paper studies whether investors’ high risk aversion can be avoided in a representative-agent model that is able to explain aggregate stock market behavior in the US financial market. We present a consumption-based asset pricing model with a representative agent who has a ‘catching up with the Joneses’ preference to show that high risk aversion can be avoided in a representative-agent model that can help explain many of the empirically observed properties of the aggregate stock market return, including the equity premium and risk-free rate puzzles, the predictability of long-horizon stock returns, and the ‘leverage effect’ in return volatility.     

From quality to innovation: Evidence from two French Employer Surveys

In this article we investigate the impact of quality systems on innovation performance using the method of propensity matching. We use two French microeconomic surveys, the “Organizational Changes and Computerization” (COI 1997) and the “Community Innovation Survey” (CIS3 1998–2000). The first hypothesis indicating that quality (ISO 9000 certification) impacts positively on innovation is supported for certain areas of innovation performance. Furthermore, the second hypothesis states that different levels of quality differentially improve innovation performance. Results indicate that the innovation performance of firms with Top Quality Level is higher than that of firms with Medium Quality Level which is also higher than that of firms with Low Quality Level for certain areas of innovation. However, we found that the difference in innovation performance between firms with Medium and Low Quality Levels is not of a great magnitude. This study implies that in order to achieve a significant innovation performance improvement via quality systems, a very well-established quality system is needed within a firm.     

The behavioral justification for public pensions: a survey

Unfunded public pension systems are primarily justified on grounds that many individuals lack sufficient capacity to appropriately save for retirement. We begin with a review of the known principle that a standard life-cycle/permanent-income consumer who discounts the future at an exponential rate can benefit from an unfunded public pension system only if the internal rate of return exceeds the private rate of return. However, a pay-as-you-go program with a below market internal rate can in fact improve lifetime utility if the consumer misestimates social security benefits, uses a hyperbolic discount function rather than the exponential function, uses a short planning horizon, behaves impulsively, or if a fraction of the population do no saving at all. A literature has consequently arisen to study how severe these behavioral defects need to be in order to justify a pay-as-you-go program. We survey this literature, and we conclude that the results are highly mixed as to whether an unfunded public pension that earns a below-market internal rate of return can be justified on grounds of shortsightedness in model economies. The challenge for this literature is that the conclusions crucially depend on the particular values of the preference parameters that are used in the simulation experiments, and these preference parameters are not observable, nor is there much consensus concerning the values that should be used in simulations. In fact, even when the analysis is confined to a small and reasonable space of the unobservable preference parameters, it is possible to reach nearly any policy conclusion. We offer some guidance for future work in this area.
