Revealing additional preference heterogeneity with an extended random parameter logit model: the case of extra virgin olive oil [PDF]
Methods that account for preference heterogeneity have received a significant amount of attention in recent literature. Most of them have focused on preference heterogeneity around the mean of the random parameters, which has been specified as a function

Planar Shuffle Product, Co-Addition and the non-associative Exponential [PDF]
In this note we introduce the concept of a shuffle product $\sq$ for planar tree polynomials and give a formula to compute the planar shuffle product $S \ \sq T$ of two finite planar reduced rooted trees $S, T.$ It is shown that $\sq$ is dual to the co-addition $\Delta$ which leads to a formula for the coefficients of $\Delta(f).$ It is also proved

New size measurements in population ecology [PDF]
In organizational ecology, we find the analysis of the impact exerted by competition between populations on vital ratios to be relatively under-developed.

On the complexity of the set of unconditional convex bodies [PDF]
We show that for any $t>1$, the set of unconditional convex bodies in $\mathbb{R}^n$ contains a $t$-separated subset of cardinality at least $\exp \exp (C(t) n)$. This implies that there exists an unconditional convex body in $\mathbb{R}^n$ which cannot be approximated within the distance $d$ by a projection of a polytope with $N$ faces unless $N ...

Egyptian Fractions with odd denominators [PDF]
The number of solutions of the diophantine equation $\sum_{i=1}^k \frac{1}{x_i}=1,$ in particular when the $x_i$ are distinct odd positive integers is investigated. The number of solutions $S(k)$ in this case is, for odd $k$: \[\exp \left( \exp \left( c_1\, \frac{k}{\log k}\right)\right) \leq S(k) \leq \exp \left( \exp \left(c_2\, k \right)\right ...

Towards functor exponentiation [PDF]
We consider a possible framework to categorify the exponential map exp(-f) given the categorification of a generator f of $\frak{sl}_2$ by Lauda. In this setup the Taylor expansions of exp(-f) and exp(f) turn into complexes built out of categorified divided powers of f.

Marginal Farmers and Agri-Environmental Schemes: Evaluating Policy Design Adequacy for the Environmental Fallow Measure [PDF]
This paper examines the factors affecting farmer's participation in an agri-environmental scheme (AES) in marginal areas implying few changes in the traditional farm management (environmental fallow).
