**A**: If bargaining is conceptualized as splitting a pie, one player prefers to cede some portion of the pie if it means the entire pie grows to a size that justifies profit-sharing. This phenomenon arises in real-world settings**B**: For instance, Apple allows third party developers to build software on iPhones. Opening up the tasks of application development to third parties improves consumer experience such that consumers are willing to purchase apps or other capabilities within apps. This additional revenue is then shared between Apple and the developer, leaving Apple with higher profits and a better product. Revenue sharing arises, often, because doing so is lucrative.**C**: The first notable take-away is that players do not necessarily opt to maximize their own proportion of the profit. Even if one player has full control over the bargaining solution, depending on the relative cost of production, they may benefit from a profit-sharing agreement in order to encourage investment by the other player

**A**: the return rates on capital depend on the amount of capital a person or household owns. More casually spoken: the richer you are, the faster your wealth grows. Detailed theoretical and empirical information on this phenomenon can be found e.g**B**: in [1, 19, 18, 2, 17]. Diverse explanations for increasing returns can be conceived, like lower risk aversion of the rich due to higher risk-bearing potential. Empirical studies in [18] confirm this idea, but on the other hand increasing returns can even be found within similar asset groups. Hence, risk is not the exclusive driver of increasing returns and other factors like higher skills, political influence, informational advantages, decreasing costs of debt, tax-evasion or lower transaction costs are relevant, too. Moreover, some asset classes are barely available for ordinary people, like private equity fonds, art or other value increasing luxury goods. **C**: Simple models assuming independent return rates (like the Black-Scholes model) can only account for exponential-tailed wealth distributions, but numerous more complex models have been proposed to find the determinants of the power-law tail, some of which can be found in [19, 21, 4, 15, 7, 39, 25, 5, 13, 26, 40, 6, 27] and references therein.

In the present work, we use the regional 2010 NUTS-2 classification as it allowed for the largest spatial and temporal coverage of the agricultural industry data**B**: Notice that, despite more recent classification are available, we adopted the NUTS 2010 nomenclature as it is the only one fully covering the 27 countries currently belonging to the European Union within the 2010-2020 period. Also, we preserve only the European regions having complete (i.e., non-missing) information for the entire time span and we removed from the analysis all the non-continental regions and the islands**C**: According to the former, we exclude from the analysis all the extra-European administrative units, such as Guyane, Martinique, and Réunion for France or Ciudad de Melilla for Spain; while according to the latter, we removed data on counties that are islands, that is, Cyprus, Ireland and Malta. We made this choice to have a specific focus on continental Europe. Indeed, while extra continental units would be clustered together due to the dominance of the geographical distance with respect to the features’ distance, the other three major islands would introduce the issue of dealing with spatial units without neighbors or with a few number of neighbors that belong to the same country. The selected dataset includes complete data for 221 NUTS-2 regions across Europe (see Figure 2 or Figure 3 for a graphical representation of the available spatial units).

Model-based “estimates” of U.S. GDP are not required, since the advance estimate of quarterly U.S. GDP is published at the end of the following month**B**: Looking across the rows of these two tables, we see considerable cross-state variation in accuracy. Looking across the columns, as hoped, we see that accuracy tends to improve as information accumulates – as we move to the right in each table. These gains are summarized in the final row of each table when reporting the RMSE and CRPS statistics averaged across states. These averaged statistics support our main finding that accuracy clearly improves in an absolute sense as more within-quarter and past-quarter information accumulates. They also indicate that the biggest jump in forecast accuracy, both for the point and density nowcasts and estimates, happens when information on the third month in the quarter (see the m3 nowcast) becomes available. Interestingly, this jump in accuracy occurs before the BEA publish their own advance estimate of quarterly U.S**C**: GDP. That is, we find that there is little gain to waiting an extra month and using the advance estimate of state GDP rather than a model-based nowcast, as long as this nowcast conditions on two months of within-quarter information. This is understood when we observe that the accuracy of the nowcasts for U.S. GDP growth also improves dramatically at m3. This means, in effect, that when computing nowcasts of state GDP at m3, the model is conditioning, via the cross-sectional aggregation constraint, on good estimates of U.S. GDP.

**A**: The main drawback of our approach is its dependence on a selection rule for choosing a candidate algorithm. When we are able to reject the null, as in our application, then the optimality properties of the selection rule (in particular, whether it satisfies improvement convergence as defined in Section 4) do not matter**B**: That is, no matter how naive or heuristic our selection rule is, we can conclude that the status quo algorithm is improvable. But when our test does not allow us to reject the null, there is in general an ambiguity: It may be that there is not sufficient evidence in the data to conclude existence of an improving algorithm; or, alternatively, it may be that the selection rule is not powerful enough to find this algorithm**C**: In the latter case, re-running the same test with a different selection rule could lead us to reject the null. This ambiguity is resolved asymptotically when the selection rule is improvement-convergent, since Theorem 4.2 establishes that our proposed test is consistent under this condition. One interesting direction for future work is thus to provide sufficient conditions for a selection rule to be improvement-convergent in different applications.

More generally, the Weber strategy of bargaining can be implemented iteratively via an additional natural Axiom 4, and it converges to a unique solution, where the resource is exhausted. **B**: The first way is to use the symmetry axiom, which postulates that the domains coincide. The second, behavioral way assumes that the players make proposals within the acceptable domain employing the previous proposal of the opponent as her baseline.

**A**: However, it is limited by its use of broad 2-digit sector level of analysis. This high-level aggregation prevents researchers from exploring finer details of sector interactions or product-specific relationships. For instance, in the automotive industry, this limitation makes it difficult to analyze the complexity of specific car parts a country imports to produce its exported vehicles, hindering a more nuanced understanding of the technological sophistication embedded in these component-level trade flows.**B**: The need to bridge these two approaches arises from their respective drawbacks and potential complementarity: EC assumes that ’what you export’ is a proxy of ’what you produce competitively’, and thus of the capabilities you are endowed with, neglecting the fragmentation of production and the import of inputs from abroad. For instance, a country may specialise in exporting final commodities like cars while importing the most technologically advanced and capabilities embedded components essential for their production**C**: This scenario can lead to misinterpretation, where a country’s success in exporting vehicles is mistakenly seen as proof of its ability to manufacture all components, including those embodying cutting-edge technology and capabilities. Recent research stresses the importance of accounting for the import dimension of trade when assessing a country’s economic capabilities in the EC framework (Ferrarini and Scaramozzino,, 2015, 2016; Bam et al.,, 2020; Koch and Schwarzbauer,, 2021; Hernández-Rodríguez et al.,, 2023; Karbevska and Hidalgo,, 2023; Sebestyén et al.,, 2024).

As agent behaviour is conditioned on the evolving characteristics, this helps mitigate the Lucas critique, adapting behaviour in response to environmental change, and, due to the bi-level design, simultaneously optimises the environment itself in response to the changing agent behaviours. We formulate the problem as a Stackelberg game, solving a coupled set of non-linear equations, and show how this subsumes several common ABM tasks, such as calibration, scenario analysis, robust behavioural learning, and policy design, under one unified framework.**B**: ADAGE automatically learns behavioural rules that adapt to environmental changes, as well as learning these potential environmental changes based on the task of the designer (e.g., for policy design or calibration)**C**: In this work, we develop a generic two-layer framework for ADaptive AGEnt-based modelling (ADAGE)

**A**: The idea of approximating semiparametric models with growing parametric models is, of course, not new, as there is a well developed literature on sieve estimation. Compared to this broad literature however, the goal of the present paper is much more specific**B**: We aim to find conditions under which we can transfer the classical efficiency results of maximum likelihood estimators of a Euclidean parameter in well-behaved parametric models to the semiparametric case. Whilst similar conclusions are reached in the sieve literature (see, e.g., Theorem 4 in Shen, (1997)), these results typically follow as special cases of more general results permitting, for example, criterion functions which are not log-likelihoods**C**: Our goal in this paper is to show that by focussing on the specific case of maximum likelihood estimation and being more specific about the behaviour of the approximating models permits a simpler and more user-friendly theory of semiparametric estimation. We show asymptotic normality and semiparametric efficiency of maximum likelihood estimators under conditions which are, we believe, simpler to both understand and verify than the often rather technical assumptions made in the sieve literature. In particular, we are able to show that this efficiency result holds in a broad class of models without imposing any empirical process type conditions. As we exemplify with the Cox model in Section 5.2, sieves might also just be used as a theoretical tool (and not for estimation), and allows for simpler efficiency proofs than those currently available.

**A**: RF’s flexibility in adjusting the weighting of the look-back window over time is evident, particularly around structural breaks**B**: In the two-sided case, we observe a sharp increase in the importance of recent lags just before an abrupt change, while leading observation weights peak right after the break. This pattern reflects RF’s ability, in the two-sided case, to capture breaks by not mixing pre- and post-break data together when computing a moving average around the sudden shift date.**C**: Figure 3 illustrates the importance of lagged (and, when applicable, leading) observations in AlbaMA, shown for both one-sided and two-sided configurations
