Financial Risk Propensity,Business Cycles and Perceived Risk Exposure

We analyse whether individual financial risk propensity changes over time with background financial conditions, as well as personal and subjective portfolio risk exposure. We elicit risk propensity from six different self‐assessed facets collected in a long panel data set from the DNB Household Survey, annually covering the period 1995–2015. Risk propensity is generally higher during periods of economic growth and lower during periods of recession, but is untrended when elicited, using questions referring to safe investments. Our risk propensity measure is also higher following positive stock market returns or subjectively large risk exposure in own past investments.     

Instagram and body image: Motivation to conform to the “Instabod” and consequences on young male wellbeing

The current paper explores how male Instagram users' (MIU) perceptions of body image and behavior are affected by the exposure to fitness hashtags, and the consequences on their wellbeing. For this purpose, in-depth interviews were conducted with #fitfam MIU with different levels of engagement. Low-engagement MIU with low body-esteem long for the “instabod” and engage in body transformation efforts to follow the fitness trend popularized by Instagram, to emulate peers and Instagram celebrities, to gain popularity and to appear successful. Instagram community members use positive and negative reinforcements to strengthen body internalization. The body transformation effort motivates low-engagement MIU to engage more, which has various effects on wellbeing: on one side, they feel anxious and in competition with other peers which often leads to muscle dysmorphia symptoms; on the other side, they feel more masculine with higher self-confidence, they have higher motivation to stay fit and to eat healthily.     

Ambiguity in Problem Framing as a Barrier to Collective Actions: Some Hints from Groundwater Protection Policy in the Apulia Region

Differences in problem framing and understanding are unavoidable in multi-actor decision-making processes, deeming ambiguous problem definitions and actions. The presence of ambiguity may have diverse implications. On the one hand, a diversity in frames can enhance the co-production of knowledge offering opportunities for innovative solutions. On the other hand, the presence of ambiguity can be a source of discrepancies or conflict in a group, hampering the implementation and/or reducing the effectiveness of environmental policy. This work demonstrates that neglecting ambiguity in problem framing leads decision-actors to simplify the interaction space by ignoring the role of some of the other decision-actors and/or making wrong assumptions about their mental models. Moreover, they act as if the system is as simple as the decision-actors presume it to be. To demonstrate these hypotheses, a Causal Loop Diagram method was implemented to investigate the policy resistance mechanisms hampering the implementation of sustainable groundwater abstraction policy in the Apulia Region (Southern Italy).     

Monetary Policy with Sectoral Trade‐Offs

We formulate a two‐sector New Keynesian economy featuring sectoral heterogeneity along three dimensions: price stickiness, consumption goods durability, and the usage of input materials in production. These factors affect both inter‐sectoral and intra‐sectoral stabilization. We examine the welfare properties of simple rules that react to alternative measures of final goods price inflation. Due to factor demand linkages, the cost of production in one sector is influenced by price‐setting in the other sector. Therefore, measures of aggregate inflation weighting sectoral prices based on their relative stickiness do not allow one to keep track of the effective speeds of sectoral price adjustment.     

Strategic inventories under limited commitment

In a dynamic storable good market where demand changes over time, we investigate the producer's strategic incentives to hold inventories in response to the possibility of buyer stockpiling. The literature on storable goods has demonstrated that buyer stockpiling in anticipation of higher future prices harms the producer's profitability, particularly when the producer cannot commit to future prices. We show that the producer's inventories act as a strategic device to mitigate the loss from the lack of commitment. Our results provide a rationale for the producer's inventory behavior that sheds new light on the well‐documented empirical evidence about inventories.     

Cost Accounting for War: Contracting Procedures and Cost-plus Pricing in WWI Industrial Mobilization in Italy

The aim of this paper is to explore the role played by cost accounting in Italy's Industrial Mobilization system and in the largest firm manufacturing weaponry, Ansaldo of Genoa, during WWI. While in other countries such as the UK and the USA, efficiency in buying and managing war material was an important part of military strategy, in Italy, various factors impeded it. This paper focuses on contracting procedures adopted by the Ministry of War and Ministry of Munitions and looks at the cost accounting practices in Ansaldo to see how costs were determined and how prices were set. We found a paradox. On the one hand, despite knowledge of costing, the government did not impose cost controls on the producers of war material, nor on their profit rates. On the other hand, examining Ansaldo's cost sheets we discover they underestimated their production costs leading the firm to losses despite its favorable political position. This paper contributes to the theoretical debate about the relationships between accounting and war in the Italian context where lobbying, collusion, bribery and private interests dominated the administrative behavior of public and private actors instead of efficiency, accountability and honesty.     

Annual use, economic life and residual value of cut-to-length harvesting machines

Recognizing the absence of up-to-date empirical data on the economic life, the annual use and the residual value of dedicated cut-to-length (CTL) harvesting machinery, the authors gathered a large database of second-hand machine sale offers containing over 1000 records, coming from Europe and North America. The statistical analysis of these data pointed at an economic life in the vicinity of 18,000 h for both harvesters and forwarders, which confirms previous assumptions. The average annual use for the machines in the database is 1424 and 1581 h year⁻¹, respectively for the harvesters and the forwarders. Nordic users achieve a higher annual use than central European users, and the difference is statistically significant. Nevertheless, the average annual use recorded for both groups falls below the levels commonly adopted in current estimates, which may therefore represent ideal reference figures rather than actual averages. Residual value is strongly related to machine age, and the authors calculated some simple functions for estimating it. The study points at a better retention of the original value, compared to the figures reported in previous literature. At 5 years of age the harvesters and forwarders in the study keep respectively 38% and 44% of the new value. The information contained in the study is crucial to machine rate calculation, which has often been based on rule-of-thumb assumptions, in the absence of empirical data.     

Consumer Standards as a Strategic Device to Mitigate Ratchet Effects in Dynamic Regulation

Strategic delegation to an independent regulator with a pure consumer standard improves dynamic regulation by mitigating ratchet effects associated with short‐term contracting. A pure consumer standard alleviates the regulator's myopic temptation to raise output after learning the firm is inefficient. Anticipating this tougher regulatory behavior, efficient firms find it less attractive to exaggerate costs. This reduces the need for long‐term rents and mitigates ratchet effects. A welfare standard biased toward consumers entails, however, allocative costs arising from partial separation of the firms' cost types. A trade‐off results, which favors strategic delegation when efficient firms are relatively likely.     

INCOMPLETE CONTRACTS MODELLING

Contractual incompleteness has been understood in the literature as the conditions under which contracts are insufficiently state contingent due to non‐observable and/or non‐verifiable states of the world. The term incomplete contracts has been used in different meanings: to denote both proper contractual incompleteness (in a complete contracts context) due to various types of information problems, which can be contractually solved through a suitably designed mechanism and a context (an incomplete contracting context) where ex ante states of nature that are too expensive to describe prevent a contractual mechanism being designed. We examine these significantly different interpretations in both methodological and formal terms. We argue that, as long as relationship‐specific investment conditions occur, an incomplete contracting context is an innovative paradigm to the extent that it permits analysis of issues that in a complete contract context cannot even be broached, namely the recognition of non‐contractible inefficiencies and the possibility of non‐contractual solutions to such inefficiencies.
