For an arbitrary Lévy process X which is not a compound Poisson process, we are interested in its occupation times. We use a quite novel and useful approach to derive formulas for the Laplace transform of the joint distribution of X and its occupation times. Our formulas are compact, and more importantly, the forms of the formulas clearly demonstrate the essential quantities for the calculation of occupation times of X. It is believed that our results are important not only for the study of… 
Occupation times of Lévy processes
In this paper, we give a complete and succinct proof that an explicit formula for the occupation time holds for all Lévy processes, which is important to the pricing problems of various
Occupation times of alternating renewal processes with Lévy applications
TLDR
A central limit theorem is established (entailing that a centered and normalized version of α(t)∕t converges to a zero-mean normal random variable as t→∞) and the tail asymptotics of ℙ(α( t)√t≥q) are established.

Abstract For refracted spectrally negative Levy processes, we identify expressions for several quantities related to the Laplace transforms of their weighted occupation times until first exit times.
Alternative approach to derive q-potential measures of refracted spectrally L\'evy processes
For a refracted L\'evy process driven by a spectrally negative L\'evy process, we use a different approach to derive expressions for its q-potential measures without killing. Unlike previous methods

Joint distribution of a spectrally negative Lévy process and its occupation time, with step option pricing in view
Abstract We study the distribution Ex[exp(-q∫0t1(a,b)(Xs)ds); Xt ∈ dy], where -∞ ≤ a < b < ∞, and where q, t > 0 and x ∈ R for a spectrally negative Lévy process X. More precisely, we identify the

Introductory Lectures on Fluctuations of Lévy Processes with Applications
Levy processes are the natural continuous-time analogue of random walks and form a rich class of stochastic processes around which a robust mathematical theory exists. Their mathematical significance

We show that the positive Wiener-Hopf factor of a Levy process with positive jumps having a rational Fourier transform is a rational function itself, expressed in terms of the parameters of the jump

For spectrally negative Levy processes, we find expressions of potential measures that are discounted by their joint occupation times over semi-infinite intervals (−∞,0) and (0,∞). These expressions
